Learn to find the LCM or two monomials

The video tutorial explains how to find the lowest common multiple (LCM) of numbers and expressions. It begins by introducing the concept of LCM and demonstrates finding the LCM of the numbers 7 and 5, which is 35. The tutorial then extends the concept to include variables, explaining how to determine the LCM when variables like A and B are involved. The video concludes with a summary and practice exercises to reinforce the learning.
