Is 72 a factor of 243?

Here we will show you two different methods you can use to determine if 72 is a factor of 243.

The first method entails simply listing all factors of 243 and then seeing if 72 is one of them. The factors of 243 are 1, 3, 9, 27, 81, and 243. Looking at the list, you see that 72 is not on the list, and the answer to "Is 72 a factor of 243?" is therefore no.

For the second and perhaps easier method, we divide 243 by 72 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 72 is a factor of 243. If the quotient is a fractional number, then 72 is not a factor of 243.

243 divided by 72 is 3.375 which is a fractional number. Thus, once again, the answer to "Is 72 a factor of 243?" is no.
