## What are Multiples of 15?

A number is called a multiple of 15 if it is completely divisible by 15 with the remainder zero.

For example, 15 divides 30 completely, so by the definition 30 is a multiple of 15. Similarly, 15, 30, 45, 60, 150, 1500, etc. are all examples of multiples of 15 as they are completely divisible 15.

Remark: From the above definition, it is clear that any multiple of 15 can be written as 15n for some integer n. Thus, the set of multiples of 15 in set-builder form is given as follows:

{15n: n is an integer}
