... Nowadays, there are programs that compute the number of primes less than n, denoted π(n), for increasingly large values of n and print out the proportion: π(n)/n. If we examine the results, we notice that the proportion of primes slowly goes downward. That is, the percentage of numbers less than a m ...

... Unique prime factorisation Theorem Any positive integer n ≥ 2 admits a prime factorisation. This factorisation is unique up to rearranging the factors. Ideas of the proof: The existence is proved by strong induction on n. It is based on a simple fact: if p1 p2 . . . ps is a prime factorisation of k ...
