For example, they viewed lines as segments that could be extended indefinitely not something infinite that we view just part of. Every case of Dirichlet's theorem yields Euclid's theorem. See Also Number theory Prime Euclid. Further Pure Mathematics. Sergio Rey-Silva Recommended for you.

proof that there are an. Euclid may have been the first to give a proof that there are infinitely many primes. 3], see the page "There are Infinitely Many Primes" for several other proofs. For this reason Euclid could not have written "there are infinitely many primes," rather he wrote "prime numbers are.

Euclid's theorem is a fundamental statement in number theory that asserts that there are bigger than n.

## Infinitely many prime numbers.

The conclusion is that the number of primes is infinite.

(by reductio ad absurdum). Assume there are a finite number, n, of primes, the largest being p n. Why are there infinitely many prime numbers?
