[6] 12 18 24 30 36
66 is the first one
The first 6 multiples of 4 are: 4, 8, 12, 16, 20, and 24.
The first 10 multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30.
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18. They are the products of 3 and the nonzero integers 1, 2, 3, 4, 5, and 6.
To get the multiples, just calculate: 6 x 1 6 x 2 etc.
That's an infinite list.
Multiples of 6 are numbers in the 6 times table. So the first 5 multiples of 6 are 6, 12, 18, 24 and 30.
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66
The first five multiples of 6 are 6, 12, 18, 24 and 30. For them to be common, they need to be compared to another set of multiples.
30, 60, 90, 120, 150
0, 2, 4, 6, 8.0,2,4,6,8 are the first five multiples of 2
