Is 3 a factor of 646?

Here we will show you two different methods you can use to determine if 3 is a factor of 646.

The first method entails simply listing all factors of 646 and then seeing if 3 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 3 is not on the list, and the answer to "Is 3 a factor of 646?" is therefore no.

For the second and perhaps easier method, we divide 646 by 3 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 3 is a factor of 646. If the quotient is a fractional number, then 3 is not a factor of 646.

646 divided by 3 is 215.3333333 which is a fractional number. Thus, once again, the answer to "Is 3 a factor of 646?" is no.
