Let m, n and k be given.
Assume Hk: k int.
Assume H1: divides_int m n.
Apply H1 to the current goal.
Assume H.
Apply H to the current goal.
Assume Hm: m int.
Assume Hn: n int.
Assume _.
rewrite the current goal using mul_SNo_com k n (int_SNo k Hk) (int_SNo n Hn) (from left to right).
We will prove divides_int m (n * k).
An exact proof term for the current goal is divides_int_mul_SNo_L m n k Hk H1.
