What is the least common factor of X squared - 64?

I think you're mixing a few concepts here. In order to find something in common with something else, you need at least two things. You have only one expression here. The least common factor of any set of integers is 1. I suspect you may want to factor this expression. There is a formula for the difference of squares. This factors to (x - 8)(x + 8) You could compare those factors to the factors of another expression to find something in common between them.
