To find the least common multiple of two numbers, they factor those numbers and take the maximum factor values to derive the LCM.
15: 3 x 5
18: 3 x 3 x 2 = 3^2 x 5
So, taking the maximum factors, one gets
2 x 3^2 x 5 = 2 x 9 x 5 = 90
90 is the least common multiple between them.
To get more multiples, just start with the least common one, and add it to itself until you derive enough multiples:
90 is the first
90 + 90 = 180 is the second
180 + 90 = 270

What are two common multiples for 18 and 36?
All multiples of 36 are multiples of 18.
What is the common multiple of 15 30 and 45?
There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.
