To find the greatest common factor (GCF) of 91, 78, and 65, we first need to find the prime factors of each number. The prime factors of 91 are 7 and 13, the prime factors of 78 are 2, 3, and 13, and the prime factors of 65 are 5 and 13. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 13. Therefore, the GCF of 91, 78, and 65 is 13.
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 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 The common factors are: 1, 13 The Greatest Common Factor: GCF = 13
13.
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.
