One place where this is used is to simplify fractions: you need to find the greatest common factor, then divide top and bottom by this greatest common factor.Also, in factoring expressions - you can take out the greatest common factor. For example (using "^" for power): 5x^2 + 10x has the greatest common factor 5x; so this can be taken out as a common factor, resulting in 5x(x + 2).
