91: 1, 7, 13, 91 78: 1, 2, 3, 6, 13, 26, 39, and 78 65: 1, 5, 13, and 65 The answer is 13
They are: 13, 26, 39, 52, 65, 78, 91
13, 26, 39, 52, 65, 78, 91.
The GCF is: 13
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.
The GCF of 26, 52, 65, and 91 is: 13
The first 4 multiples of 13 are: 13, 26, 39, and 52.
The multiples of 13 from 1 to 100 are: 13, 26, 39, 52, 65, 78, 91.
The GCF is 13.
