This cannot be answered because the common multiples of any two or more numbers are infinite.
There is no limit to the amount of common multiples. Numbers are infinite. If you take an example of a common multiple such as 360 then you can just keep adding noughts to it forever ie 3600 36000 etc and i'ts still a common multiple of 15 and 18.
