There are infinitely many common multiples of 6 and 8. The least common multiple of them is 24. After that, all of the multiples of 24 (i.e., 48, 72, 96, etc.) are the common multiples of 6 and 8.
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 multiples of 6 is 6,12,18,24,30,36,42,48,54,60,66,72,78,84,90.................. The multiples of 9 is 9,18,27,36,45,54,63,72,81,90,99,108,117,126,135...............
6 of them
Multiples of 6: 1,2,3,6 Multiples of 4: 1,2,4 Multiples of 3: 1,3
10
Half of them. Any number that is a multiple of 6 is also a multiple of 3 and 2.
15*6 = 90 and 15*7 = 105 so there are 6 multiples.
Multiples of any multiple of 6.

6
4 of them.
The multiples of 6 is 6,12,18,24,30,36,42,48,54,60,66,72,78,84,90.................. The multiples of 9 is 9,18,27,36,45,54,63,72,81,90,99,108,117,126,135...............
All the multiples of 24 are also multiples of 6.
Oh, what a happy little question! To find the multiples of 4 and 6 below one thousand, we need to see how many times each number fits into 1000. For 4, we divide 1000 by 4 to get 250 multiples. For 6, we divide 1000 by 6 to get 166 multiples. But wait, we've counted the multiples of 24 twice, so we need to subtract those extras to find the total number of unique multiples.
There are 10 multiples of 6 in that range.
