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
A multiple in math is any number that is the product of that number. For example 2, 4, 6 and 8 are multiples of 2. So the first 5 multiples of 42 are 42, 84, 126, 168 and 210.
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.
Since the GCF of 5 and 6 is 1, their LCM is their product. The first five multiples of 30 are 30, 60, 90, 120, 150
2, 4, 6, 8, 10, 12.
