Is 15 a factor of 10?

Here we will show you two different methods you can use to determine if 15 is a factor of 10.

The first method entails simply listing all factors of 10 and then seeing if 15 is one of them. The factors of 10 are 1, 2, 5, and 10. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 10?" is therefore no.

For the second and perhaps easier method, we divide 10 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 10. If the quotient is a fractional number, then 15 is not a factor of 10.

10 divided by 15 is 0.666666667 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 10?" is no.
