The least common multiples of 5, 11, and 13 is 715.
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
It is 12 and its multiples.
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.
The least common multiples of the numbers 3,4 and 6 would be 12. This is a math problem.
