Is 9 a factor of 145?

Here we will show you two different methods you can use to determine if 9 is a factor of 145.

The first method entails simply listing all factors of 145 and then seeing if 9 is one of them. The factors of 145 are 1, 5, 29, and 145. Looking at the list, you see that 9 is not on the list, and the answer to "Is 9 a factor of 145?" is therefore no.

For the second and perhaps easier method, we divide 145 by 9 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 9 is a factor of 145. If the quotient is a fractional number, then 9 is not a factor of 145.

145 divided by 9 is 16.11111111 which is a fractional number. Thus, once again, the answer to "Is 9 a factor of 145?" is no.
