Is 15 a factor of 128?

Here we will show you two different methods you can use to determine if 15 is a factor of 128.

The first method entails simply listing all factors of 128 and then seeing if 15 is one of them. The factors of 128 are 1, 2, 4, 8, 16, 32, 64, and 128. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 128?" is therefore no.

For the second and perhaps easier method, we divide 128 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 128. If the quotient is a fractional number, then 15 is not a factor of 128.

128 divided by 15 is 8.533333333 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 128?" is no.
