What are Multiples of 3?
A number is called a multiple of 3 if it is completely divisible by 3 with the remainder zero.
For example, 3 divides 9 completely, so by the definition 9 is a multiple of 3. Similarly, 9, 12, 15, 18, 30, 300, etc. are all examples of multiples of 3 as they are completely divisible 3.
Remark: From the above definition, it is clear that any multiple of 3 can be written as 3n for some integer n. So the set of multiples of 3 is given by
{3n: n is an integer}
