(Euclid) There exist an infinite number of primes. Proof. Suppose that there are a finite number of primes, say p 1, p 2, ..., p n. Let N = p 1p 2 ···p n + 1. By the fundamental theorem of arithmetic, N is divisible by some prime p. This prime p must be among the p i, since by WebHammond, Louisiana 150 views, 2 likes, 4 loves, 4 comments, 4 shares, Facebook Watch Videos from Victory Baptist Church: VBC Live!

So we assume that there exist integers x and y such that x and y are odd and there exists an integer z such that x2 + y2 = z2. Since x and y are odd, there exist integers m and n such that x = 2m + 1 and y = 2n + 1.
