56: 1, 2, 4, 7, 8, 14, 28, 56

7: 1, 7

The greatest common factor is 7

Answer 2

The greatest common factor (GCF) is defined as the greatest number that two or more numbers can be multiplied by to get the number without exceeding it. To find the GCF of 56 and 7, we can list what numbers multiply to get both 7 and 56:

7: 1, 7 because 1 • 7 = 7

56: 1, 2, 4, 7, 8, 14, 28, 56 because all of the numbers can be multiplied by a number within the set to get an output of 56.

Because the greatest number in both sets is 7, we can conclude that the greatest common factor of 56 and 7 is 7.
