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.
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
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, . . .
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.
