Here we will show you two different methods you can use to determine if 3 is a factor of 126.

The first method entails simply listing all factors of 126 and then seeing if 3 is one of them. The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 126?" is therefore yes.

For the second and perhaps easier method, we divide 126 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 126. If the quotient is a fractional number, then 3 is not a factor of 126.

126 divided by 3 is 42 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 126?" is yes.
