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 first three multiples of 2 are 2, 4, 6. For them to be common, they need to be compared to another set of multiples.
The first three common multiples of 2 and 3 are... 6, 12 and 18.
first multiples of 2 are 2,4,6 then for 3 3,6,9 for 5 is 5,10,15
The first three common multiples of 6 and 8 are the first three multiples of the least common multiple of 6 and 8. 6 = 2 x 3 and 8 = 2 x 2 x 2. Therefore, the LCM of 6 and 8 is 2 x 2 x 2 x 3 or 24. The first three multiples of 24 are 24, 48 and 72.
4, 8 and 12 are the first 3 common multiples of 2 and 4

2, 4, 6
The first three multiples of 235 are 235, 470 and 705. For them to be common, they need to be compared to another set of multiples. The first three common multiples of 2, 3 and 5 are 30, 60 and 90.
12, 24, and 36
