Find the GFC of 56 and 84.

28

Step-by-step explanation:

The factor must be less than 56, and it must be a factor of 56. So, start listing the factors of 56. The first one you get is by dividing 56 by 2: 56 / 2 = 28. Now, is 28 a factor of 84? Start multiplying it and find out: 28 * 2 = 56 (which we already knew) 28 * 3 = 84. So, yes, 28 is the greatest common factor of 56 and 84.
