Lesson Summary:

In this lesson, you'll learn about the least common multiple (LCM) and how to find it for a set of numbers. There are different methods to find the LCM, including listing all the multiples and using prime factorization. The LCM is the smallest number that all the given numbers divide into without a remainder. The video suggests checking out other videos for easier ways to find the LCM.

Lesson Description:
