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.
