Proof step 2 from proof gcd-primes (previous step)

prime(i), prime(j) ⊦ gcd(i, j) = 1, i = j

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-gcd inst: name: gcd-one seq: ⊦ gcd(i, j) = 1 ↔ ¬(∃ i1. i1 > 1 ∧ i1 | i ∧ i1 | j) subst: [j, i] → [j, i] flags: rewrite, current

Additional information

Used terms: j, i
