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 = 3x3
PF of 12 = 2x2x3
PF of 18 = 2x3x3
Thus, LCM is 3x3x2x2 = 36
Common multiples can be found by multiplying 36(LCM) with 1, 2, 3,...etc.

What are the first 6 multiples of 6 and 9?
The common multiples of 6 and 9 are the infinite set of multiples of their LCM, which is 18. So the common multiples of 6 and 9 are 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, and so on.
What is the first three common multiples of 2 3 and 9?
To find the common multiples of 2, 3, and 9, we first need to list out the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, and so on. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and so on. The first three common multiples of 2, 3, and 9 are 18, 36, and 54.
What are the first 5 common multiples of 9?
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
What are the common multiples of 2 and 9?
Oh, what a happy little question! When we talk about multiples, we're looking at numbers that both 2 and 9 can be divided into evenly. The common multiples of 2 and 9 are numbers like 18, 36, 54, and so on - just like little friends skipping along together in the meadow.
