You multiply 6, 7, and 8 until all answers are the same. For example, the common multiples of 3 and 7 would be 21, because:
3,6,9,12,15,18,21
7,14,21
See how they both have the common multiples?
Hope this helped!
The first three multiples of 6 are 6, 12 and 18. For them to be common, they need to be compared to another set of multiples.
First common multiples are also know as the least common multiples (LCM) the answer is................ 168
First three common multiples of 5 and 6 are 30, 60 and 90.
The first multiple is the LCM of 6, 7 and 8. Then you find LCM*2 and LCM*3.
The first three common multiples of 2 and 3 are... 6, 12 and 18.

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.
First three common multiples of 5 and 6 are 30, 60 and 90.
You can not find the least common multiple of just one number. You can find the multiples of 147 but have nothing to compare it to to find the "least" first 6 multiples of 147 - 147, 294, 441, 588, 735, 882
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
The first multiple is the LCM of 6, 7 and 8. Then you find LCM*2 and LCM*3.
The first three common multiples of 2 and 3 are... 6, 12 and 18.
