Life is good, but it can always get better. Just imagine being able to find the smallest number that is a multiple of two other numbers! It's called the LCM or Least Common Multiple. Other than making your life more fulfilling, lcm will allow you to do incredible things like adding fractions. Common Core Standard: 6.NS.B.4
You know how to find factors of a number, but what about factors that are common to two numbers? Even better, imagine the largest factors that are common to two numbers.
