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
