Is 3 a factor of 129?

Here we will show you two different methods you can use to determine if 3 is a factor of 129.

The first method entails simply listing all factors of 129 and then seeing if 3 is one of them. The factors of 129 are 1, 3, 43, and 129. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 129?" is therefore yes.

For the second and perhaps easier method, we divide 129 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 129. If the quotient is a fractional number, then 3 is not a factor of 129.

129 divided by 3 is 43 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 129?" is yes.
