Is 78 a factor of 155?

Here we will show you two different methods you can use to determine if 78 is a factor of 155.

The first method entails simply listing all factors of 155 and then seeing if 78 is one of them. The factors of 155 are 1, 5, 31, and 155. Looking at the list, you see that 78 is not on the list, and the answer to "Is 78 a factor of 155?" is therefore no.

For the second and perhaps easier method, we divide 155 by 78 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 78 is a factor of 155. If the quotient is a fractional number, then 78 is not a factor of 155.

155 divided by 78 is 1.987179487 which is a fractional number. Thus, once again, the answer to "Is 78 a factor of 155?" is no.
