Is 3 a factor of 210?

Here we will show you two different methods you can use to determine if 3 is a factor of 210.

The first method entails simply listing all factors of 210 and then seeing if 3 is one of them. The factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, and 210. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 210?" is therefore yes.

For the second and perhaps easier method, we divide 210 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 210. If the quotient is a fractional number, then 3 is not a factor of 210.

210 divided by 3 is 70 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 210?" is yes.
