Table Of Prime Factors - Wikipedia

The tables contain the prime factorization of the natural numbers from 1 to 1000.

When n is a prime number, the prime factorization is just n itself, written in bold below.

The number 1 is called a unit. It has no prime factors and is neither prime nor composite.

Properties

[edit]

Many properties of a natural number n {\displaystyle n} can be seen or directly computed from the prime factorization of n {\displaystyle n} .

• The multiplicity of a prime factor p {\displaystyle p} of n {\displaystyle n} is the largest exponent m {\displaystyle m} for which p m {\displaystyle p^{m}} divides n {\displaystyle n} . The tables show the multiplicity for each prime factor. If no exponent is written then the multiplicity is 1 {\displaystyle 1} (since p = p 1 {\displaystyle p=p^{1}} ). The multiplicity of a prime which does not divide n {\displaystyle n} may be called 0 {\displaystyle 0} or may be considered undefined.
• ω ( n ) {\displaystyle \omega (n)} and Ω ( n ) {\displaystyle \Omega (n)} , the prime omega functions, count the number of prime factors of a natural number n {\displaystyle n} .
  • ω ( n ) {\displaystyle \omega (n)} (little omega) is the number of distinct prime factors of n {\displaystyle n} .
  • Ω ( n ) {\displaystyle \Omega (n)} (big omega) is the number of prime factors of n {\displaystyle n} counted with multiplicity (so it is the sum of all prime factor multiplicities).
• A prime number has Ω ( n ) = ω ( n ) = 1 {\displaystyle \Omega (n)=\omega (n)=1} . The first: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 (sequence A000040 in the OEIS). There are many special types of prime numbers.
• A composite number has Ω ( n ) ≥ ω ( n ) > 1 {\displaystyle \Omega (n)\geq \omega (n)>1} . The first: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21 (sequence A002808 in the OEIS). All numbers above 1 are either prime or composite. 1 is neither.
• A semiprime has Ω ( n ) = 2 {\displaystyle \Omega (n)=2} (so it is composite). The first: 4, 6, 9, 10, 14, 15, 21, 22, 25, 26, 33, 34 (sequence A001358 in the OEIS).
• A k {\displaystyle k} -almost prime (for a natural number k {\displaystyle k} ) has Ω ( n ) = k {\displaystyle \Omega (n)=k} (so it is composite if k > 1 {\displaystyle k>1} ).
• An even number has the prime factor 2. The first: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 (sequence A005843 in the OEIS).
• An odd number does not have the prime factor 2. The first: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 (sequence A005408 in the OEIS). All integers are either even or odd.
• A square has even multiplicity for all prime factors (it is of the form a 2 {\displaystyle a^{2}} for some a {\displaystyle a} ). The first: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 (sequence A000290 in the OEIS).
• A cube has all multiplicities divisible by 3 (it is of the form a 3 {\displaystyle a^{3}} for some a {\displaystyle a} ). The first: 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, 1331, 1728 (sequence A000578 in the OEIS).
• A perfect power has a common divisor m > 1 {\displaystyle m>1} for all multiplicities (it is of the form a m {\displaystyle a^{m}} for some a > 1 {\displaystyle a>1} and m > 1 {\displaystyle m>1} ). The first: 4, 8, 9, 16, 25, 27, 32, 36, 49, 64, 81, 100 (sequence A001597 in the OEIS). 1 is sometimes included.
• A powerful number (also called squarefull) has multiplicity greater than 1 for all its prime factors. The first: 1, 4, 8, 9, 16, 25, 27, 32, 36, 49, 64, 72 (sequence A001694 in the OEIS).
• A prime power has only one prime factor, i.e. ω ( n ) = 1 {\displaystyle \omega (n)=1} . The first: 2, 3, 4, 5, 7, 8, 9, 11, 13, 16, 17, 19 (sequence A000961 in the OEIS). 1 is sometimes included.
• An Achilles number is powerful but not a perfect power. The first: 72, 108, 200, 288, 392, 432, 500, 648, 675, 800, 864, 968 (sequence A052486 in the OEIS).
• A square-free integer has no prime factor with multiplicity greater than 1. The first: 1, 2, 3, 5, 6, 7, 10, 11, 13, 14, 15, 17 (sequence A005117 in the OEIS). A number where some but not all prime factors have multiplicity greater than 1 is neither square-free nor squarefull, but squareful.
• The Liouville function λ ( n ) {\displaystyle \lambda (n)} is 1 if Ω ( n ) {\displaystyle \Omega (n)} is even, and is -1 if Ω ( n ) {\displaystyle \Omega (n)} is odd.
• The Möbius function μ ( n ) {\displaystyle \mu (n)} is 0 if n {\displaystyle n} is not square-free. Otherwise μ ( n ) {\displaystyle \mu (n)} is 1 if Ω ( n ) {\displaystyle \Omega (n)} is even, and is −1 if Ω ( n ) {\displaystyle \Omega (n)} is odd.
• A sphenic number is square-free and the product of 3 distinct primes, i.e. it has ω ( n ) = Ω ( n ) = 3 {\displaystyle \omega (n)=\Omega (n)=3} . The first: 30, 42, 66, 70, 78, 102, 105, 110, 114, 130, 138, 154 (sequence A007304 in the OEIS).
• a 0 ( n ) {\displaystyle a_{0}(n)} , sometimes called the integer logarithm, is the sum of primes dividing n {\displaystyle n} , counted with multiplicity. It is an additive function.
• A Ruth-Aaron pair is a pair of two consecutive numbers ( n , n + 1 ) {\displaystyle (n,n+1)} with a 0 ( n ) = a 0 ( n + 1 ) {\displaystyle a_{0}(n)=a_{0}(n+1)} . The first (by n {\displaystyle n} value): 5, 8, 15, 77, 125, 714, 948, 1330, 1520, 1862, 2491, 3248 (sequence A039752 in the OEIS). Another definition is where the same prime is only counted once; if so, the first (by n {\displaystyle n} value): 5, 24, 49, 77, 104, 153, 369, 492, 714, 1682, 2107, 2299 (sequence A006145 in the OEIS).
• A primorial p n # {\displaystyle p_{n}\#} is the product of all primes from 2 to p n {\displaystyle p_{n}} . The first: 2, 6, 30, 210, 2310, 30030, 510510, 9699690, 223092870, 6469693230, 200560490130, 7420738134810 (sequence A002110 in the OEIS). 1 # = 1 {\displaystyle 1\#=1} is sometimes included.
• A factorial n ! {\displaystyle n!} is the product of all numbers from 1 to n {\displaystyle n} . The first: 1, 2, 6, 24, 120, 720, 5040, 40320, 362880, 3628800, 39916800, 479001600 (sequence A000142 in the OEIS). 0 ! = 1 {\displaystyle 0!=1} is sometimes included.
• A k {\displaystyle k} -smooth number (for a natural number k {\displaystyle k} ) has its prime factors ≤ k {\displaystyle \leq k} (so it is also j {\displaystyle j} -smooth for any j > k {\displaystyle j>k} ).
• m {\displaystyle m} is smoother than n {\displaystyle n} if the largest prime factor of m {\displaystyle m} is less than the largest of n {\displaystyle n} .
• A regular number has no prime factor greater than 5 (so it is 5-smooth). The first: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16 (sequence A051037 in the OEIS).
• A k {\displaystyle k} -powersmooth number has all p m ≤ k {\displaystyle p^{m}\leq k} where p {\displaystyle p} is a prime factor with multiplicity m {\displaystyle m} .
• A frugal number has more digits than the number of digits in its prime factorization (when written like the tables below with multiplicities above 1 as exponents). The first in decimal: 125, 128, 243, 256, 343, 512, 625, 729, 1024, 1029, 1215, 1250 (sequence A046759 in the OEIS).

• An extravagant number has fewer digits than its prime factorization. The first in decimal: 4, 6, 8, 9, 12, 18, 20, 22, 24, 26, 28, 30 (sequence A046760 in the OEIS).
• An economical number has been defined as a frugal number, but also as a number that is either frugal or equidigital.
• g c d ( m , n ) {\displaystyle gcd(m,n)} (greatest common divisor of m {\displaystyle m} and n {\displaystyle n} ) is the product of all prime factors which are both in m {\displaystyle m} and n {\displaystyle n} (with the smallest multiplicity for m {\displaystyle m} and n {\displaystyle n} ).
• m {\displaystyle m} and n {\displaystyle n} are coprime (also called relatively prime) if they have no common prime factors, which implies g c d ( m , n ) = 1 {\displaystyle gcd(m,n)=1} .
• l c m ( m , n ) {\displaystyle lcm(m,n)} (least common multiple of m {\displaystyle m} and n {\displaystyle n} ) is the product of all prime factors of m {\displaystyle m} or n {\displaystyle n} (with the largest multiplicity for m {\displaystyle m} or n {\displaystyle n} ).
• g c d ( m , n ) × l c m ( m , n ) = m × n {\displaystyle gcd(m,n)\times lcm(m,n)=m\times n} . Finding the prime factors is often harder than computing g c d {\displaystyle gcd} and l c m {\displaystyle lcm} using other algorithms which do not require known prime factorization.
• m {\displaystyle m} is a divisor of n {\displaystyle n} (also called m {\displaystyle m} divides n {\displaystyle n} , or n {\displaystyle n} is divisible by m {\displaystyle m} ) if all prime factors of m {\displaystyle m} have at least the same multiplicity in n {\displaystyle n} .
• The divisors of n {\displaystyle n} are all products of some or all prime factors of n {\displaystyle n} (including the empty product 1 of no prime factors). The number of divisors can be computed by increasing all multiplicities by 1 and then multiplying them.

Divisors and properties related to divisors are shown in table of divisors.
