The multiples of 36 go on forever.
Common multiples of 9 and 10 are all of the multiples of 90.
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
The common multiples of 4 and 9 are 36, 72, 108 and so on.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.

Common multiples of 7 and 4 include any multiple of 28.
They are the first three multiples of their lowest common multiple: 36, 72, 108.
All multiples of 90.
Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
The LCM of 4, 9, and 12 is 36
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.
Any multiple of 36.
