Is 23 a factor of 357?

Here we will show you two different methods you can use to determine if 23 is a factor of 357.

The first method entails simply listing all factors of 357 and then seeing if 23 is one of them. The factors of 357 are 1, 3, 7, 17, 21, 51, 119, and 357. Looking at the list, you see that 23 is not on the list, and the answer to "Is 23 a factor of 357?" is therefore no.

For the second and perhaps easier method, we divide 357 by 23 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 23 is a factor of 357. If the quotient is a fractional number, then 23 is not a factor of 357.

357 divided by 23 is 15.52173913 which is a fractional number. Thus, once again, the answer to "Is 23 a factor of 357?" is no.
