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

⊦ gcd(m, n) = gcd(n, m % n), n = 0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 3:
m = m0 * n + n0 ∧ n0 < n ⊦ gcd(m, n) = gcd(n, n0), n = 0

Rule argument

spec: nat-div inst: name: div-elim seq: n ≠ 0 ⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n subst: [m, n, m0, n0] → [m, n, m0, n0] flags:

Additional information

Used simplifier rules: n ≠ 0 ⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n; (elim) Used terms: m, n, m0, n0
