Theorem pcmptdvds 16823

Description: The partial products of the prime power map form a divisibility chain. (Contributed by Mario Carneiro, 12-Mar-2014.)

**Hypotheses**
Ref	Expression
pcmpt.1	⊢ 𝐹 = (𝑛 ∈ ℕ ↦ if(𝑛 ∈ ℙ, (𝑛↑𝐴), 1))
pcmpt.2	⊢ (𝜑 → ∀𝑛 ∈ ℙ 𝐴 ∈ ℕ₀)
pcmpt.3	⊢ (𝜑 → 𝑁 ∈ ℕ)
pcmptdvds.3	⊢ (𝜑 → 𝑀 ∈ (ℤ_≥‘𝑁))

**Assertion**
Ref	Expression
pcmptdvds	⊢ (𝜑 → (seq1( · , 𝐹)‘𝑁) ∥ (seq1( · , 𝐹)‘𝑀))

Proof of Theorem pcmptdvds Dummy variables 𝑚 𝑝 are mutually distinct and distinct from all other variables.
