What is the greatest common factor of 63 81 and 72?

Answer 1

Alright, buckle up buttercup. The greatest common factor of 63, 81, and 72 is 9. That's right, 9 is the big winner here. So, next time you're staring at a bunch of numbers, just remember that good ol' 9 is there to save the day.

Answer 2

To find the greatest common factor (GCF) of 63, 81, and 72, we first need to find the prime factorization of each number.

The prime factorization of 63 is 3 x 3 x 7, the prime factorization of 81 is 3 x 3 x 3 x 3, and the prime factorization of 72 is 2 x 2 x 2 x 3 x 3.

The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 3 x 3 = 9. Therefore, the greatest common factor of 63, 81, and 72 is 9.

Answer 3

The GCF is 9.

Answer 4

GCF(63, 81, 72) = 9.
