Is 45 a factor of 12?

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

The first method entails simply listing all factors of 12 and then seeing if 45 is one of them. The factors of 12 are 1, 2, 3, 4, 6, and 12. Looking at the list, you see that 45 is not on the list, and the answer to "Is 45 a factor of 12?" is therefore no.

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

12 divided by 45 is 0.266666667 which is a fractional number. Thus, once again, the answer to "Is 45 a factor of 12?" is no.
