All natural numbers can be divided into two groups of numbers: simple and composite.

A prime number – is a number that has only two divisors (one and this number itself), i.e. is divided without a remainder only by one and by itself. It is generally accepted that unit (1) is not a prime number. Example of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, etc. The prime numbers are an infinite set, below are the prime numbers up to 1000.

A composite number – is a number that has more than two divisors. Any composite number can be in the form of produced prime numbers, for example: 84 = 2 · 2 ·3 ·7.
