Is 55 a factor of 390?

Here we will show you two different methods you can use to determine if 55 is a factor of 390.

The first method entails simply listing all factors of 390 and then seeing if 55 is one of them. The factors of 390 are 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, and 390. Looking at the list, you see that 55 is not on the list, and the answer to "Is 55 a factor of 390?" is therefore no.

For the second and perhaps easier method, we divide 390 by 55 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 55 is a factor of 390. If the quotient is a fractional number, then 55 is not a factor of 390.

390 divided by 55 is 7.090909091 which is a fractional number. Thus, once again, the answer to "Is 55 a factor of 390?" is no.
