Is 12 a factor of 45?

Here we will show you two different methods you can use to determine if 12 is a factor of 45.

The first method entails simply listing all factors of 45 and then seeing if 12 is one of them. The factors of 45 are 1, 3, 5, 9, 15, and 45. Looking at the list, you see that 12 is not on the list, and the answer to "Is 12 a factor of 45?" is therefore no.

For the second and perhaps easier method, we divide 45 by 12 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 12 is a factor of 45. If the quotient is a fractional number, then 12 is not a factor of 45.

45 divided by 12 is 3.75 which is a fractional number. Thus, once again, the answer to "Is 12 a factor of 45?" is no.
