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.

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.
