What is the least common multiple of both 9 and 12

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
