Is 15 a factor of 15?

Here we will show you two different methods you can use to determine if 15 is a factor of 15.

The first method entails simply listing all factors of 15 and then seeing if 15 is one of them. The factors of 15 are 1, 3, 5, and 15. Looking at the list, you see that 15 is on the list, and the answer to "Is 15 a factor of 15?" is therefore yes.

For the second and perhaps easier method, we divide 15 by 15 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 15 is a factor of 15. If the quotient is a fractional number, then 15 is not a factor of 15.

15 divided by 15 is 1 which is a whole number. Thus, once again, the answer to "Is 15 a factor of 15?" is yes.
