Is 5 a factor of 646?

Here we will show you two different methods you can use to determine if 5 is a factor of 646.

The first method entails simply listing all factors of 646 and then seeing if 5 is one of them. The factors of 646 are 1, 2, 17, 19, 34, 38, 323, and 646. Looking at the list, you see that 5 is not on the list, and the answer to "Is 5 a factor of 646?" is therefore no.

For the second and perhaps easier method, we divide 646 by 5 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 5 is a factor of 646. If the quotient is a fractional number, then 5 is not a factor of 646.

646 divided by 5 is 129.2 which is a fractional number. Thus, once again, the answer to "Is 5 a factor of 646?" is no.
