LCM stands for least common multiple.
This is found by listing multiples of each number until you reach a number that each number shares.
A multiple is the result from when the given number is multiplied by an integer.
When listing multiples, multiply the specified number by 1, then 2, then 3, and so on until all given numbers have reached a point where a number has shown up in both of the lists of multiples.
Multiples of 9:
9 • 1 = 9
9 • 2 = 18
9 • 3 = 21
9 • 4 = 36
Multiples of 12:
12 • 1 = 12
12 • 2 = 24
12 • 3 = 36
36 is the first multiple, meaning the lowest, that is common and shared between 9 and 12. This makes 36 the LCM of 9 and 12.
Answer:
36 is the LCM (least common multiple) of 9 and 12.
Hope this helps!
