Video Trailer:  How to find the LCM of 2 or more numbers.

 

VIDEO DESCRIPTION: A two step process on how to find the LCM (least common multiple) of 2 or more numbers by prime factorization is presented.

The first step is to write each of the numbers we have to find their LCM as a product of prime numbers.

The second step is to take each of the prime numbers that are in the products in step 1 in their highest power and write all of them as a product. This will be the LCM of the numbers that we are looking to find their LCM

An illustrated example on the topic follows.
