There exists infinite common multiples of 9, 12 & 18.But, the least common multiple is only one which can be found by the factorization of each number:PF of 9 = 3x3PF of 12 = 2x2x3PF of 18 = 2x3x3Thus, LCM is 3x3x2x2 = 36Common multiples can be found by multiplying 36(LCM) with 1, 2, 3,...etc.
LCM is 72
