Proof step 11 from proof gcd-one-eq (
previous step
)
j2 / gcd(i2, j2) = 1, 0 < j2, 0 < gcd(i2, j2) ⊦ gcd(i2, j2) = j2, gcd(i2, j2) = 0, j2 = 0, gcd(i2, j2) | j2
User applied rule apply lemma
And obtained the following new goals
Proof step 12
:
⊦ gcd(i, j) | j
Rule argument
spec: <toplevel> name: gcd-div2 seq: ⊦ gcd(i, j) | j subst: [i, j] → [i2, j2]
Additional information
Used terms: i2, j2
