Proof step 4 from proof gcd-div-rest (previous step)

i = i1 * gcd(i, j) + j0, abs(j0) < gcd(i, j) ⊦ j0 = 0

User applied rule insert lemma

And obtained the following new goals

Proof step 5:
⊦ gcd(i, j) | i
Proof step 6:
gcd(i, j) | i, i = i1 * gcd(i, j) + j0, abs(j0) < gcd(i, j) ⊦ j0 = 0

Rule argument

spec: int-gcd inst: name: gcd-div1 seq: ⊦ gcd(i, j) | i subst: [i, j] → [i, j] flags: current, []
