| gcd(gcd(m, n), n0) | m ∧ gcd(gcd(m, n), n0) | gcd(n, n0) → gcd(gcd(m, n), n0) | gcd(m, gcd(n, n0)) ⊦ gcd(gcd(m, n), n0) | gcd(m, gcd(n, n0)) |
⊦ gcd(m, n) = gcd(n, m)
gcd(gcd(n, m), n0) | m ∧ gcd(gcd(n, m), n0) | gcd(n, n0) → gcd(gcd(n, m), n0) | gcd(m, gcd(n, n0)) ⊦ gcd(gcd(n, m), n0) | gcd(m, gcd(n, n0))
Used terms: n, m
