QUESTION:

For exercises 28 and 29, use the fact that for all integers n, n! = n(n − 1) . . . \(3 \cdot 2 \cdot 1\).

An alternative proof of the infinitude of the prime numbers begins as follows:

Proof: Suppose there are only finitely many prime numbers. Then one is the largest. Call it p. Let M = p! + 1.We will show that there is a prime number q such that q > p. Complete this proof.
