Is 3 a factor of 320?

Here we will show you two different methods you can use to determine if 3 is a factor of 320.

The first method entails simply listing all factors of 320 and then seeing if 3 is one of them. The factors of 320 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, and 320. Looking at the list, you see that 3 is not on the list, and the answer to "Is 3 a factor of 320?" is therefore no.

For the second and perhaps easier method, we divide 320 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 320. If the quotient is a fractional number, then 3 is not a factor of 320.

320 divided by 3 is 106.6666667 which is a fractional number. Thus, once again, the answer to "Is 3 a factor of 320?" is no.
