Proof step 5 from proof gcd-div-mult-shift (
previous step
)
⊦ i = 0, i / gcd(i, j) * j0 = (i * j0) / gcd(i, j), gcd(i, j) = 0, gcd(i, j) | i
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 6
:
⊦ gcd(i, j) | i
Rule argument
spec: int-gcd inst: name: gcd-div1 seq: ⊦ gcd(i, j) | i subst: [j, i] → [j, i] flags: rewrite, current
Additional information
Used terms: j, i
