Step 5: Take 5 and divide with 28. The remainder will be 3. But factors always give 0 remainder. This means 5 is NOT a factor of 28. Step 6: Take 6 and divide with 28. The remainder will be 4. This means 6 is NOT a factor of 28. Step 7: Take 7 and divide with 28. It gives 7 x 4 = 28 but factors 7 and 4 are already in the list. So you dont need to repeat the number.
