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.
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 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
The GCF is 13.
The GCF is 52.
104 / 91 =1 r 13 91 / 13 = 7 r 0 gcf of 104 and 91 is 13
The factors of 91 are:1, 7, 13, 91The factors of 104 are:1, 2, 4, 8, 13, 26, 52, 104The common factors are:1, 13The Greatest Common Factor:GCF = 13
The GCF is 13.
It is: 13
Since 52 is a factor of 104, it is automatically the GCF.
The GCF of 26, 52, and 104 is 13
The GCF is 13.
The GCF is: 13
It is: 728
The GCF of 26, 52, 65, and 104 is 13.
