The LCM or least common multiple of 9, 12, 4, and 18 is 36.
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.
M of 6 = (6,12,18,24,30,36......) M of 9 = (9,18,27,36....) Here, CM =18,36..... Where LCM = 18 (Which is Lowest Common Multiple of 6 and 9)
The LCM is 180.
The LCM of 2, 9, and 18 is 18. Because 18 is a multiple of both 2 and 9, it is automatically the LCM.You can also find the LCM by listing the multiples of each number, then finding the lowest multiple that is found in each list.Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, and so on.Multiples of 9 are 9, 18, 27, and so on.Multiples of 18 are 18, 36, 54, and so on.So the LCM of 2, 9, and 18 is 18.It is 18
