What are Multiples of 1?

A number is called a multiple of 1 if it is completely divisible by 1 with the remainder zero.

For example, 1 divides 2 completely, so by the definition 2 is a multiple of 1. Similarly, 1, 4, 5, 8, 11, 100, etc. are all examples of multiples of 1 as they are completely divisible 1.

Remark: From the above definition, it is clear that any multiple of 1 can be written as 1n for some integer n. So the set of multiples is given by

{1n: n is an integer}= the set of integers.
