List the multiples of each number until at least one of the multiples appears on all lists
Find the smallest number that is on all of the lists
This number is the LCM
Example: LCM(6,7,21)
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60
Multiples of 7: 7, 14, 21, 28, 35, 42, 56, 63
Multiples of 21: 21, 42, 63
Find the smallest number that is on all of the lists. We have it in bold above.
So LCM(6, 7, 21) is 42
