The least common multiple can be found by prime factorization or simpy listing the factors! You must know what the least common multiple that goes into 9 and 12.
Prime factorization of 9 and 12 is 3 so 3x2x2x3=36
Or you can list the factors
9:   9,18,24,36
12: 12,24,36
So the least common multiple is 36

LCM is found by finding the factors of both and making sure that both are inthere
9=3 times 3
12=2 times 2 times 3
common one is 3
so we have to have at least 2 threes and 2 twos
2 times 2 times 3 tiimes 3=36
answer is 36
