# Lesson 96 – Doodles Do Algebra

Today your child learns about the relationship between least common multiple and greatest common factor. The least common multiple is the least quantity that contains the quantities exactly and the greatest common factor contains all the factors common to the quantities. So if you multiply together all the quantities and divide them by their greatest common factor, you will be left with the least common multiple.

1. $24a^4x^2y(a+x)$
2. $12a^2(a-x)(a+x)x^4$
3. $24a^4x^3y^2(x-y)$
4. $60a^2x^5(x+y)(x-y)^2$
