The first 2 multiples are 42,84.
That's going to depend on where you start and in which direction you go. If you begin at zero and move in the direction of increasing numbers, then the first three multiples of 3 are 3, 6, and 9, the first three multiples of 2 are 2, 4, and 6, and the first three COMMON multiples of 2 AND 3 that you'll encounter are 6, 12 and 18.

The most common multiples are 13 3 3234 2 2 2 2 232
The first 4 multiples of 1 are: 1, 2, 3, and 4.
4, 8 and 12 are the first 3 common multiples of 2 and 4
12
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
Get the first common multiple, then multiply that by 0, 1, 2, 3, 4, etc. to get additional common multiples.
The first 5 multiples of 1 are: 1, 2, 3, 4, and 5.
