Proof step 15 from proof equality-01 (previous step)

i = i0 / gcd(i0, j0) * gcd(i, j), j = j0 / gcd(i0, j0) * gcd(j, i), 0 < j, 0 < j0 ⊦ j = 0, i * j0 = i0 * j, j0 = 0, i0 = 0, i = 0

User applied rule insert equation

And obtained the following new goals

Proof step 16:
i = i0 / gcd(i0, j0) * gcd(i, j), j = j0 / gcd(i0, j0) * gcd(j, i), 0 < j, 0 < j0 ⊦ j = 0, (i0 / gcd(i0, j0) * gcd(i, j)) * j0 = i0 * j, j0 = 0, i0 = 0, i = 0

Rule argument
