Overview
The Greatest Common Factor, or GCF, is the largest factor that two numbers have in common. A factor is any positive number that when mulitplied by another positive number will equal the number you are trying to find factors for. For example, the number 2. The only factors of 2 are 1 and 2, because both 1 and 2 can be multiplied by another number to equal 2. When finding the GCF, you will be finding the factors for 2 or more numbers. and then comparing them. Your GCF is the highest number that they all have in common.
