Is 3 a factor of 120?

Here we will show you two different methods you can use to determine if 3 is a factor of 120.

The first method entails simply listing all factors of 120 and then seeing if 3 is one of them. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 120?" is therefore yes.

For the second and perhaps easier method, we divide 120 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 120. If the quotient is a fractional number, then 3 is not a factor of 120.

120 divided by 3 is 40 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 120?" is yes.
