What are Multiples of 20?

A number is called a multiple of 20 if it is completely divisible by 20 with the remainder zero.

For example, 20 divides 40 completely, so by the definition 40 is a multiple of 20. Similarly, 20, 40, 60, 80, 100, 200, 2000, etc. are all examples of multiples of 20 as they are completely divisible 20.

Remark: From the above definition, it is clear that any multiple of 20 can be written as 20n for some integer n. So the set of multiples is given by

{20n: n is an integer}
