Solution 2. Prime factorizing , we see . The sum of 's odd divisors are the sum of the factors of without , and the sum of the even divisors is the sum of the odds subtracted by the total sum of divisors. The sum of odd divisors is given by and the total sum of divisors is Thus, our ratio is. ~JustinLee2017.
Notice that now Re and Im = Im. This forces and to be equal to and , meaning that all three are equally spaced along the unit circle. We can now show that we can construct complex numbers when that do not satisfy the conditions in the problem. Suppose that the condition in the problem holds for some .
