Since all other whole numbers (except 0) can be produced by multiplying together primes – they must be considered fundamental.
(1), 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 &etc
There are an infinite number of primes - as proved by Euclid around 300B.C. ( Ref. ). Although billions of them have so far been found (nowadays via computational 'sieving' algorithms), they appear to be randomly distributed - but with some 'rules' (see links below). As yet there’s no proven mathematical method which can accurately predict where the next one will be.
