Assuming you mean positive whole numbers, then all numbers greater than 1 can be factorised using prime numbers only.
Some of the numbers are prime themselves, eg 2, 3, 5, 7 and so factorise into themselves; others are composite and so factorise into the product of 2 primes, eg 8 = 2 x 2 x 2, 12 = 2 x 2 x 3
