We choose not to regard 1 as a prime number, simply because it makes writing lots of theorems much easier. Noah gives the best example in his answer: Euclid's theorem that every positive integer can be written uniquely as a product of primes

What's prime number?

Prime number is a number which divisible by itself and 1.

Let's put this condition to 1(One).
1 is divisible by itself I.e. 1.
and as per condition 1 is also divisible by 1.

Since,
The number of first condition = The number of second condition

So,
1 can not be considered a prime number as it is divisible by only single number.
