To find common multiples you first need to break up the numbers into their prime factors. In this case:
4=2x2
9=3x3
12=2x2x3
The next step is to identify common factors and discard the duplicates. Two numbers have two 2s so we can discard two of these. Also, two numbers have a 3, so we can discard 1 of these. That leaves us with 2, 2, 3 and 3. Multiply these together for the LCM:
2x2x3x3 = 36
To find other multiples, you simply multiply the LCM by 1,2,3 etc.
So the first three common multiples are 36, 72 and 108.

What are the multiples of 5 8 and 12?
24, 48, 72, 96, 120
What are the first three common multiples of three eight and nine?
8 and 9 are corpime, so their first common multiple is their product. The next common multiples are simply the multiples of that first multiple.The first three common multiples are therefore 72, 144 and 216.
What are two common multiples of 8 and 9?
The common multiples of 9 and 16 are 144, 288, 432 and so on.
What are the common multiples for 9 and 12?
36, 72, 108 and so on.
What are the first 2 multiples of 8 and 12?
The first thing you should notice is that both 8 and 12 are evenly divisible by 2. This means that any common multiples of 8 and 12 will also be multiples of 2. So we only really need to find the first three common multiples of 8 and 12.First common multiple: 248 * 3 = 2412 * 2 = 24(2 * 12 = 24)Second common multiple: 488 * 6 = 4812 * 4 = 48(2 * 24 = 48)Second common multiple: 728 * 9 = 7212 * 6 = 72(2 * 36 = 72)
What is all the common multiples of 8 and 9 and 12?
LCM is 72
What are all the common multiples of 8 and 9 that are less than 100 and how?
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
What are the first 3 common multiples of 7 8 and 9?
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
