It is not possible to write all the common multiples of two or more numbers.However, we can write as many as we want but first of all we have to find L.C.M. of 49 and 14 and the answer is 98.Also, multiples of 98 are the common multiples of 49 and 14.It means that multiples of least common factor of two or more numbers are the common multiples of the numbers.So, first five common multiples are 98x1, 98x2, 98x3, 98x4 and 98x5.

Two common multiples of 21 and 15 are 105 and 315.

6 multiples of 7 are: 14, 21, 28, 35, 42, and 49
