## What's a prime number?

A prime number is a natural number greater than 1 and that has only two divisors (1 and the prime number).
2 is the first prime number and the unique even number to be prime number. All whole numbers that are greater than 1 and
that are not prime numbers are called composite numbers.

Here are prime numbers between 1 et 100:
** 2; 3; 5; 7; 11; 13; 17; 19; 23; 29; 31; 37; 41; 43; 47; 53; 59; 61; 67; 71; 73; 79; 83; 89; 97**.

All prime numbers are odd numbers except 2.
