**The Greatest Common Factor (G.C.F.)**

The Greatest Common Factor (G.C.F.) also known as

the greatest common divisor (GCD) or highest common

factor (HCF) of two numbers is the largest number that is a

divisor of both.

Example:

4 is the GCF of 8 and 12. Why? Because 4 is the largest

number that divides evenly (without a remainder) into 8

and 12

Factors of 8 are 1, 2, 4, and 8

The factors of 12 are 1, 2, 3, 4, 6 and 12
