A decent video that shows the steps necessary for finding the least common multiple among three numbers, this resource could prove useful in or out of class. You might give this to learners to use as a reference while they complete homework, or show it in class to complement your lesson.

A common multiple is exactly what it says it is: a multiple that two or more numbers have in common. So then a least common multiple would be the smallest common multiple that two or more numbers have in common. Watch this video to see how the instructor identifies common multiples of two different numbers.

In this least common multiples practice worksheet, students examine sample problems and solve 20 problems that require them to find least common multiples.

Don't get Least Common Multiple mixed up with Greatest Common Factor, it's easy to do. Use the prime factor tree to find the prime factorization of each of the terms given. This is where it gets tricky figuring out the LCM, so watch this video and follow the instructor as she demonstrates how to determine the Least Common Multiple.

Looking for the least common multiple, not the greatest common factor. It's so easy to mix these up. It may seem a little confusing at first because there are variables and exponents in the monomial examples. Watch this video and get some practice as the instructor walks through the steps.

In this least common multiple learning exercise, students write numbers as a product of primes to determine the least common multiple. Explanations and examples are provided. This two-page learning exercise contains ten problems.

Give students detailed instructions on how to find the Least Common Multiple as well as practice with this thorough introductory worksheet. Instructions for this worksheet include an explanation of both guess and check as well as prime factorization method as ways of finding a LCM for two numbers. Additionally the practice section provides eight multiple choice problems which can be completed as a worksheet or an interactive online quiz.
