Is 4 a factor of 20?

Here we will show you two different methods you can use to determine if 4 is a factor of 20.

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

For the second and perhaps easier method, we divide 20 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 20. If the quotient is a fractional number, then 4 is not a factor of 20.

20 divided by 4 is 5 which is a whole number. Thus, once again, the answer to "Is 4 a factor of 20?" is yes.
