Proof step 2 from proof divi-primmult (previous step)

prime(m), m | n * n0 ⊦ m | n, m | n0

User applied rule cut formula

And obtained the following new goals

Proof step 3:
gcd(m, n) = 1, prime(m), m | n * n0 ⊦ m | n, m | n0
Proof step 5:
prime(m), m | n * n0 ⊦ gcd(m, n) = 1, m | n, m | n0

Rule argument

fma: gcd(m, n) = 1

Additional information

Used formulas: gcd(m, n) = 1
