What is the greatest common factor of 91 21 and 49?
The greatest common factor (GCF) of three numbers is the largest number that divides each of the three numbers without leaving a remainder. To find the GCF of 91, 21, and 49, we need to factorize each number. The prime factors of 91 are 7 and 13, the prime factors of 21 are 3 and 7, and the prime factors of 49 are 7 and 7. The common factor among them is 7, so the GCF of 91, 21, and 49 is 7.
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.
