Is 36 a factor of 639?

Here we will show you two different methods you can use to determine if 36 is a factor of 639.

The first method entails simply listing all factors of 639 and then seeing if 36 is one of them. The factors of 639 are 1, 3, 9, 71, 213, and 639. Looking at the list, you see that 36 is not on the list, and the answer to "Is 36 a factor of 639?" is therefore no.

For the second and perhaps easier method, we divide 639 by 36 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 36 is a factor of 639. If the quotient is a fractional number, then 36 is not a factor of 639.

639 divided by 36 is 17.75 which is a fractional number. Thus, once again, the answer to "Is 36 a factor of 639?" is no.
