Least Common Multiple

A few reminders for LCM:

A multiple is the product of two numbers. 10 is a multiple of both 2 and 5, for example. Be careful not to confuses multiples with factors.

When finding the LCM using prime factorization, use each match only once, and then bring all the other numbers "down to the party."

If you are finding the LCM of three numbers, your common factors ("matches") do NOT need to be found in all three numbers to be considered a match.
