3, 6, 9, 12, 15, 18, 21, 24, 27, 30
EG List the first 10 multiples of 2 and 3.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
3, 6, 9, 12, 15, 18, 21, 24, 27, 30
Notice some of the numbers are in both lists, these are common multiples
Lowest Common Multiple
As the name suggests, this is the smallest number in the list of common multiples.
Lowest Common Multiple
EG Find the LCM for 4 and 6.
