Is 15 a factor of 122?

Here we will show you two different methods you can use to determine if 15 is a factor of 122.

The first method entails simply listing all factors of 122 and then seeing if 15 is one of them. The factors of 122 are 1, 2, 61, and 122. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 122?" is therefore no.

For the second and perhaps easier method, we divide 122 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 122. If the quotient is a fractional number, then 15 is not a factor of 122.

122 divided by 15 is 8.133333333 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 122?" is no.
