Theorem infpnlem1 12359

Description: Lemma for infpn 12361. The smallest divisor (greater than 1) 𝑀 of 𝑁! + 1 is a prime greater than 𝑁. (Contributed by NM, 5-May-2005.)

**Hypothesis**
Ref	Expression
infpnlem.1	⊢ 𝐾 = ((!‘𝑁) + 1)

**Assertion**
Ref	Expression
infpnlem1	⊢ ((𝑁 ∈ ℕ ∧ 𝑀 ∈ ℕ) → (((1 < 𝑀 ∧ (𝐾 / 𝑀) ∈ ℕ) ∧ ∀𝑗 ∈ ℕ ((1 < 𝑗 ∧ (𝐾 / 𝑗) ∈ ℕ) → 𝑀 ≤ 𝑗)) → (𝑁 < 𝑀 ∧ ∀𝑗 ∈ ℕ ((𝑀 / 𝑗) ∈ ℕ → (𝑗 = 1 ∨ 𝑗 = 𝑀)))))

Distinct variable groups: 𝑗,𝑁 𝑗,𝑀 𝑗,𝐾
