The least common multiple — introduction

This is an introduction to the least common multiple of two numbers. The term itself tells you what this means: we need to check the MULTIPLES of the two numbers, find the common ones, and choose the least of those. Examples make this idea clear.




The 2nd part, I explain two topics:

  • Using the least common multiple of the denominators when adding fractions; and
  • How to find the least common multiple of two numbers by using the prime factorization of the numbers.
