The lowest common multiple is 18. The first four common multiples are thus the first four multiples of 18 and are: 18, 36, 54 and 72.
Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, . . . Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, . . .
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
16, 32, 48. Since 16 is divisible by 4. Every multiple of 16 is also a multiple of 4, so I just took the first 3 multiples of 16.

First, factor: 16 = 2*2*2*2 18 = 2*3*3 Multiply the factors (only count overlapping ones once) to find the least common multiple (LCM) LCM = 2*2*2*2*3*3 = 144 The multiples of 16 and 18 are {144, 288, 432, 576...}
The first common multiple of 16 and 18 is 144. To find the common multiples of two numbers, you can list the multiples of each number and look for the smallest number that appears in both lists. The multiples of 16 are 16, 32, 48, 64, 80, 96, 112, 128, 144, etc. The multiples of 18 are 18, 36, 54, 72, 90, 108, 126, 144, etc. The smallest number that is common to both lists is 144.
The lowest common multiple is 18. The first four common multiples are thus the first four multiples of 18 and are: 18, 36, 54 and 72.
