Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι be given.
Apply H1 with
divides_int x0 (mul_SNo x2 x1).
Apply H2 with
(∃ x3 . and (x3 ∈ int) (mul_SNo x0 x3 = x1)) ⟶ divides_int x0 (mul_SNo x2 x1).
Apply mul_SNo_com with
x2,
x1,
λ x3 x4 . divides_int x0 x4 leaving 3 subgoals.
Apply int_SNo with
x2.
The subproof is completed by applying H0.
Apply int_SNo with
x1.
The subproof is completed by applying H4.
Apply divides_int_mul_SNo_L with
x0,
x1,
x2 leaving 2 subgoals.
The subproof is completed by applying H0.
The subproof is completed by applying H1.
