What Are The Multiples Of 20? [Solved] - Cuemath

Multiples of 20

From a multiplication fact, we better understand what multiples are. We know that 4 × 20 = 80. This implies 80 is the 4th multiple of 20. Multiples of 20 are obtained basically by adding 20 as many times to get the answer you want. For example, 20 + 20 = 40 or 2 × 20 = 40.

• First five multiples of 20: 20, 40, 60, 80 and 100
• Prime Factorization of 20: 20 = 2 × 2 × 5

Let us explore more about the multiples of 20 and its properties.

What are the Multiples of 20?

• Multiples of 20 are the product obtained by multiplying the numbers with 20.
• 20 can be repeatedly added to get its successive multiples.
• The 15th multiple of 20 is 20 x 15 = 300. This list of multiples is never-ending, we can generate infinite multiples of 20.
• The multiples of  20 are also the multiples of its factors. The factors of 20 are 1, 2, 4, 5, 10 and 20. 40 is the 2nd multiple of 20. 40 is also a multiple of 2, 4, 5, 10 and 20.

List of First 20 Multiples of 20

The first 20 multiples of 20 are obtained by multiplying 20 with each of the natural numbers from 1 to 20. Since multiplication is the repeated addition, once we find the first multiple, we can add 20 to it to get another multiple and we can keep adding 20 to get the successive multiples.

To understand the concept of finding multiples, let us take a few more examples.

• Multiples of 10 - The first five multiples of 10 are 10, 20, 30, 40, 50
• Multiples of 30 - The first five multiples of 30 are 30, 60, 90, 120 and 150
• Multiples of 18 - The first five multiples of 18 are 18, 36, 54, 72 and 90
• Multiples of 21- The first five multiples of 21 are 21, 42, 63, 84 and 105
• Multiples of 16 - The first five multiples of 16 are 16, 32,  48, 64 and 80

Important Notes

• A number can have infinite multiples.
• 20 is an even number, so its multiples will also be even.
• All the multiples of 20 will be the multiples of the factors of 20 as well.
