Euclids theorem says that there are infinitely many primes. Proof: Assume for a contradiction that there are finitely many primes. p1,p2,p3,...,pn Let N p1p2p3...pn 1 Claim: N is not prime because it is larger than each of p1, p2,...,pn.

r, s are elements of integers, and 1 r,s N Since 1 r,s N, both r and s can be expressed as products of primes. But then N rs is a product of primes, contradicting our choice of N. Thus our assumption is false, and every integer 1 is a product of primes

Assume for a contradiction that there exists an integer greater than one that is NOT a product of primes. Let N be the smallest such integer. If N is prime, then N is a product of one prime. So N cant be prime, thus N is composite ie N equals rs where...
