Prime Number

A prime number is a positive integer that can only be divided by 1 and itself, which means that 1 and itself are the only two factors of it. Prime For example 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 33. Those numbers can be written as below:

2 = 1 x 2

3 = 1 x 3

7 = 1 x 7
11 = 1 x 11
17 = 1 x 17

Is 1 a Prime Number?

Based on the prime definition above, 1 is not a prime number due to the fact that 1 can only be divided by one or itself. This means that 1 is the only factor of 1. Not like those prime numbers which have two factors each.
