Is 66 a factor of 689?

Here we will show you two different methods you can use to determine if 66 is a factor of 689.

The first method entails simply listing all factors of 689 and then seeing if 66 is one of them. The factors of 689 are 1, 13, 53, and 689. Looking at the list, you see that 66 is not on the list, and the answer to "Is 66 a factor of 689?" is therefore no.

For the second and perhaps easier method, we divide 689 by 66 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 66 is a factor of 689. If the quotient is a fractional number, then 66 is not a factor of 689.

689 divided by 66 is 10.43939394 which is a fractional number. Thus, once again, the answer to "Is 66 a factor of 689?" is no.
