Is 20 a factor of 100?

Here we will show you two different methods you can use to determine if 20 is a factor of 100.

The first method entails simply listing all factors of 100 and then seeing if 20 is one of them. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Looking at the list, you see that 20 is on the list, and the answer to "Is 20 a factor of 100?" is therefore yes.

For the second and perhaps easier method, we divide 100 by 20 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 20 is a factor of 100. If the quotient is a fractional number, then 20 is not a factor of 100.

100 divided by 20 is 5 which is a whole number. Thus, once again, the answer to "Is 20 a factor of 100?" is yes.
