Sorry I meant outputs, autocorrect on my phone is silly. 2n/d' would be less than 2. But it can only be 1 if it's an integer in which case d' = 2n anyway. I don't see yet how this advanced the proof though.

Ok, yea that's right. Is n = f(2n) because of the function definition that it outpours the largest distinct divisibe integer?

Homework Statement Let PosZ = {z ∈ Z : z > 0}. Consider the function f : PosZ → PosZ dened as follows: • f(1) = 1 • If z ∈ PosZ and z > 1 then f(z) is the largest integer that divides z but is distinct from z. (For example f(41) = 1 and f(36) = 18.) Prove that f is surjective...
