The least common multiple (LCM) of two numbers is the smallest that the two numbers have in common. Finding the LCM can help you with other skills, such as finding with like denominators. Let's try it with 6 and 8.
First, list a few multiples of each number.
6: 6, 12, 18, 24, 30, 36, 42, 48...
8: 8, 16, 24, 32, 40, 48, 56, 64...
Next, look at the common multiples. Find the smallest one.
6: 6, 12, 18, 24, 30, 36, 42, 48...
8: 8, 16, 24, 32, 40, 48, 56, 64...
So, the LCM of 6 and 8 is 24!
