What is the GCF of 52 78 91 and 117?

Answer 1

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

Answer 2

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 3
