Is 27 a factor of 561?

Here we will show you two different methods you can use to determine if 27 is a factor of 561.

The first method entails simply listing all factors of 561 and then seeing if 27 is one of them. The factors of 561 are 1, 3, 11, 17, 33, 51, 187, and 561. Looking at the list, you see that 27 is not on the list, and the answer to "Is 27 a factor of 561?" is therefore no.

For the second and perhaps easier method, we divide 561 by 27 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 27 is a factor of 561. If the quotient is a fractional number, then 27 is not a factor of 561.

561 divided by 27 is 20.77777778 which is a fractional number. Thus, once again, the answer to "Is 27 a factor of 561?" is no.
