Proof step 22 from proof equal-same (previous step)

j ≠ 0, i = (i0 * gcd(i, j)) / gcd(i0, j), j = (j * gcd(j, i)) / gcd(j, i0), 0 < j ⊦ i0 = 0, j = 0, i = i0, i = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
j = (j * gcd(j, i)) / gcd(j, i0), i = (i0 * gcd(i, j)) / gcd(i0, j), 0 < j ⊦ j = 0, i = 0, i = i0, i0 = 0

Rule argument

Additional information

Used simplifier rules: ⊦ gcd(i, j) = gcd(j, i);
