Proof step 2 from proof coprime-divides-03 (previous step)

gcd(i, j) = 1, i | j0 * j ⊦ i | j0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ gcd(i, j) = 1 ∧ i | j * j0 → i | j0

Rule argument

spec: int-gcd inst: name: coprime-divides-01 seq: ⊦ gcd(i, j) = 1 ∧ i | j * j0 → i | j0 subst: [i, j, j0] → [i, j, j0] flags: rewrite, current

Additional information

Used simplifier rules: commutativity: ⊦ i * j = j * i; from specification int-mult Used terms: i, j, j0
