So either n! + 1 is itself a prime, or it is divisible by a prime > n and of course ≤ n! + 1. For n = 1 and n = 2 the condition holds. So to prove the statement assume n > 2. WebMar 9, 2024 · Prime number A prime number is an integer greater than 1 whose only factors are 1 and itself. A factor is an integer that can be divided evenly into another number.
