Step 1
Factor both numbers into ' factors, identify the common factors and multiply them together.
For example, find the GCF of 56 and 84 as follows:
56 = 2 × 2 × 2 × 7
84 = 2 × 2 × 3 × 7
G C F ( 56 , 84 ) = 2 × 2 × 7 = 28

Step 1
Given two numbers, divide the larger by the smaller to find a quotient and remainder. If the remainder is zero then the smaller number was the GCF. Otherwise, repeat with the smaller number and the remainder.
Example: find the GCF of 112 and 70:
112 70 = 1 with remainder 42
70 42 = 1 with remainder 28
42 28 = 1 with remainder 14
28 14 = 2 with remainder 0
So G C F ( 112 , 70 ) = 14
