Practice: GCF and LCM of monomials
Practice problems with solutions on the GCF and LCM of monomials: two and three monomials, negative coefficients, monomials with no common variable and working backward.
Review the lessonWork each problem out on paper before you open the solution. If your answer is off, compare the steps and find where you went wrong. If a problem stops you cold, go back to the lesson: every set links to it.

Practice 8Quick check
What is the GCF of \(a^3b^2\) and \(a^5b\)?
Shared variables with the smaller exponents: \(a^3\) and \(b^1\). \(a^5b^2\) is the LCM.
Practice 9Quick check
What is the LCM of \(2x\) and \(7y\)?
\(\text{LCM}(2, 7) = 14\), and the LCM needs every variable.
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
