Is 15 a factor of 17?

Here we will show you two different methods you can use to determine if 15 is a factor of 17.

The first method entails simply listing all factors of 17 and then seeing if 15 is one of them. The factors of 17 are 1 and 17. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 17?" is therefore no.

For the second and perhaps easier method, we divide 17 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 17. If the quotient is a fractional number, then 15 is not a factor of 17.

17 divided by 15 is 1.133333333 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 17?" is no.
