"WebS does not contain any of the p i. Yet it is a nonempty subset of N, because it contains m. Thus, by well-ordering, S has a smallest element q. We claim that q is prime. For if it has a divisor q0such that 1 < q0< q, then q0would also divide m, contradicting the minimality of q. 1.7.Warning: The above proof does not imply that m itself is prime.
