Webhence φ(n) = n − 1. It was proved in class that the latter condition implies n is prime. Indeed, let d be a divisor of n with 1 ≤ d < n. Since d divides n, we have d = gcd(d,n) = 1, the last equality following from the fact φ(n) = n − 1. We deduce that the only positive divisors of n are itself and 1, that is n is prime. Exercise 3.
