Is 66 a factor of 690?

Here we will show you two different methods you can use to determine if 66 is a factor of 690.

The first method entails simply listing all factors of 690 and then seeing if 66 is one of them. The factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, and 690. Looking at the list, you see that 66 is not on the list, and the answer to "Is 66 a factor of 690?" is therefore no.

For the second and perhaps easier method, we divide 690 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 690. If the quotient is a fractional number, then 66 is not a factor of 690.

690 divided by 66 is 10.45454545 which is a fractional number. Thus, once again, the answer to "Is 66 a factor of 690?" is no.
