How do you find common multiple?

Answer 1

1.take 2 numbers

2.make both the numbers into their smallest dividends (which are equal to the number when multiplied together, the best way to do this is by using a tree diagram)

3.find out the most amount of times each dividends are in one of the numbers that you are going to be finding the lowest common multiple, not the smallest dividends

4.multiply the numbers you got from step 3 for the lcm

example:

6 4

3x2 2x2

3x2x2=12

if you dont want the LOWEST common multiple:

1. find the lowest common multiple

2. multiply it by any whole positive number and youll end up with a common multiple

Answer 2

Common multiples are multiples that go into the number you are trying to find the common multiple of.
Multiply the numbers together.
