The Fundamental Theorem of Arithmetic 
et us begin by noticing that, in a certain sense, there are two kinds of natural number: composite numbers, and prime numbers. Composite numbers are numbers we get by multiplying together other numbers. For example, 6 = 2 × 3. We say that 2 and 3 are factors of 6 (or, equivalently, that they are divisors of 6). Some numbers, however, have no factors other than themselves and one. Such numbers are called prime, and there are infinitely many of these.Primes = { 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, ... }(By convention, we don’t consider 1 to be prime – it has a special status all its own.)
