A greatest common factor is the largest factor between two or more numbers. For example, the greatest common factor of 10 and 12 is 2. Because the factors of 10 are 1,2,5, and 10 and the factors of 12 are 1,2,3,4,6, and 12. Since 2 is the largest factor that they both share, it is the greatest common factor.
