Many times in mathematics we want to reverse the distributive property. This lesson focuses on doing just that except we only examine reversing the number part of the distributive property. For example, we want to convert 22a + 2 into 2(11a+1). So how do we do this? We want to find the greatest common factor (GCF) for the coefficients, that is, the largest number that divides both coefficients. Some people can just look at the coefficients and tell. But that becomes really difficult when there are larger numbers involved. Let\'s get some steps down that always work and then look at an example. Factor the GCF from 247n  13
