Is 63 a factor of 66?

Here we will show you two different methods you can use to determine if 63 is a factor of 66.

The first method entails simply listing all factors of 66 and then seeing if 63 is one of them. The factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. Looking at the list, you see that 63 is not on the list, and the answer to "Is 63 a factor of 66?" is therefore no.

For the second and perhaps easier method, we divide 66 by 63 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 63 is a factor of 66. If the quotient is a fractional number, then 63 is not a factor of 66.

66 divided by 63 is 1.047619048 which is a fractional number. Thus, once again, the answer to "Is 63 a factor of 66?" is no.
