Products of lists of prime elements.

This file contains some theorems relating Prime and products of Lists.

theorem Prime.dvd_prod_iff {M : Type u_1} [CommMonoidWithZero M] {p : M} {L : List M} (pp : Prime p) : p ∣ L.prod ↔ ∃ a ∈ L, p ∣ a

Prime p divides the product of a list L iff it divides some a ∈ L

theorem Prime.not_dvd_prod {M : Type u_1} [CommMonoidWithZero M] {p : M} {L : List M} (pp : Prime p) (hL : ∀ a ∈ L, ¬p ∣ a) : ¬p ∣ L.prod

theorem mem_list_primes_of_dvd_prod {M : Type u_1} [CommMonoidWithZero M] [IsCancelMulZero M] [Subsingleton Mˣ] {p : M} (hp : Prime p) {L : List M} (hL : ∀ q ∈ L, Prime q) (hpL : p ∣ L.prod) : p ∈ L

theorem perm_of_prod_eq_prod {M : Type u_1} [CommMonoidWithZero M] [IsCancelMulZero M] [Subsingleton Mˣ] {l₁ l₂ : List M} : l₁.prod = l₂.prod → (∀ p ∈ l₁, Prime p) → (∀ p ∈ l₂, Prime p) → l₁.Perm l₂
