Is 15 a factor of 120?

Here we will show you two different methods you can use to determine if 15 is a factor of 120.

The first method entails simply listing all factors of 120 and then seeing if 15 is one of them. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. Looking at the list, you see that 15 is on the list, and the answer to "Is 15 a factor of 120?" is therefore yes.

For the second and perhaps easier method, we divide 120 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 120. If the quotient is a fractional number, then 15 is not a factor of 120.

120 divided by 15 is 8 which is a whole number. Thus, once again, the answer to "Is 15 a factor of 120?" is yes.
