Proof step 5 from proof max_prime_divisor-ge2 (previous step)

i / max_prime_divisor(i) < i, 0 < i, i / max_prime_divisor(i) < 2, 0 ≤ i, 2 ≤ i, ¬ prime(i) ∧ 2 ≤ i → max_prime_divisor(i) | i ⊦ prime(i)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: divides seq: ⊦ i | j ↔ (∃ i0. i * i0 = j) subst: [j, i] → [i, max_prime_divisor(i)] flags: <all paths>

Additional information

Used terms: i, max_prime_divisor(i)
