What is the GCF of 52 78 91 and 117?

Answer 1

To find the Greatest Common Factor (GCF) of 52, 78, 91, and 117, we first need to find the prime factorization of each number. The prime factorization of 52 is 2^2 * 13, 78 is 2 * 3 * 13, 91 is 7 * 13, and 117 is 3^2 * 13. The common prime factors among these numbers are 13. Therefore, the GCF of 52, 78, 91, and 117 is 13.

Answer 2

The GCF is 13.
The factors of 52 are:

1, 2, 4, 13, 26, 52

The factors of 78 are:

1, 2, 3, 6, 13, 26, 39, 78

The factors of 91 are:

1, 7, 13, 91

The factors of 117 are:

1, 3, 9, 13, 39, 117

The common factors are:

1, 13

The Greatest Common Factor (GCF) is:

13

Answer 3

GCF(52, 78, 91, 117) = 13
