0, 2, 4, 6, 8.0,2,4,6,8 are the first five multiples of 2
Since 2 is a multiple of 6, all multiples of 6 are also multiples of 2.
the first 6 multiples of 6 are: 6, 12, 18, 24, 30, and 36
The common multiples of 6 and 9 are the infinite set of multiples of their LCM, which is 18. So the common multiples of 6 and 9 are 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, and so on.
the first 6 multiples of 12 are 12,24,36,48,60, and 72.
First three common multiples of 2 and 6 are 6, 12 and 18.
0, 2, 4, 6, 8.0,2,4,6,8 are the first five multiples of 2
6 and 12.
2,4,6,8,10,12
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.
2, 4, 6, 8, 10, 12
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.
2 4 6
2, 4, 6, 8.
2, 4, 6, 8, 10, 12.
seventy two
If we multiply 18 by 1, 2, 3, 4, 5, and 6 we will get the answers 18, 36, 54, 72, 90 and 108.
