The common multiples of 2 and 9 are 18, 36, 54, 72, etc.
There is an infinite number of common multiples for 2 and 9. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
The common multiples of 9 and 11 are 99, 198, 297 and so on.
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
The lowest common multiple of 7 and 9 is 63. The common multiples of 7 and 9 are therefore the infinite set of multiples of 63. Thus, the common multiples of 7 and 9 are 63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693, and so on.
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
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.
Since the lowest common multiple of 9 and 2 is 18, all of the common multiples of 9 and 2 are multiples of 18. The first five are: 18, 36, 54, 72, 90 Since 9 is odd thean there are going to be odd numbers, which are not multiples of two.
Common multiples of 9 and 10 are all of the multiples of 90.

24 = 3 x 2 x 2 x 29 = 3 x 3prime common multiples = 3common multiples = 1,3
lowest common multiple is 18
18.
They are 36 and 72
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
Because 9 is a multiple of 3, the common multiples of 3 and 9 are the multiples of 9. The first 10 common multiples of 3 and 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and 90.
Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.
