To identify the GCF of 91 and 78, you first need to break these down into their prime factors:
91 = 7x13
78 = 2x3x13
The next step is to identify any common prime factors. In this case, both numbers have 13 as a prime factor. Thus the greatest common factor of 91 and 78 is 13.

What is the greatest common factor of 77 49 91?
The GCF is 7.
What is the greatest common factor of 44 77 and 91?
To find the greatest common factor (GCF) of 44, 77, and 91, we first need to factorize each number. The factors of 44 are 1, 2, 4, 11, 22, and 44. The factors of 77 are 1, 7, 11, and 77. The factors of 91 are 1, 7, 13, and 91. The common factor among all three numbers is 11. Therefore, the greatest common factor of 44, 77, and 91 is 11.
What is the greatest common factor of 49 77 and 91?
The greatest common factor (GCF) of 49, 77, and 91 is 7. To find the GCF, you first need to find the prime factors of each number: 49 = 7 x 7, 77 = 7 x 11, and 91 = 7 x 13. Then, identify the common prime factors among the numbers, which in this case is 7. Therefore, the GCF of 49, 77, and 91 is 7.
What is the greatest common factor of 28 77 and 99?
7 is the Greatest Common Factor (GCF) Factored into their prime factors: 28 = 2 x 2 x 7 77 = 7 x 11 91 = 7 x 13 The only factor they have in common (other than 1) is 7
What is the greatest common factor for 52 and 91?
Greatest common factor for 52 and 91 is 13.
