Is 15 a factor of 331?

Here we will show you two different methods you can use to determine if 15 is a factor of 331.

The first method entails simply listing all factors of 331 and then seeing if 15 is one of them. The factors of 331 are 1 and 331. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 331?" is therefore no.

For the second and perhaps easier method, we divide 331 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 331. If the quotient is a fractional number, then 15 is not a factor of 331.

331 divided by 15 is 22.06666667 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 331?" is no.
