### Why is the sum of the reciprocals of all of the divisors of a perfect number equal to 2?

Suppose N is a perfect number. Then N cannot be a square number
and so N has an even number of factors.Suppose the factors are f(1)
=1, f(2), f(3), ... , f(k-1), f(k)=N.
Furthermore f(r) * f(k+1-r) = N for r = 1, 2, ... k so that f(r)
= N/f(k+1-r)
which implies that 1/f(r) = f(k+1-r)/N
Then 1/f(1) + 1/(f(2) + ... + 1/f(k)
= f(k)/N + f(k-1)/N + ... + f(1)/N
= [f(k) + f(k-1) + ... + f(1)] / N
= 2N/N since, by definition, [f(k) + f(k-1) + ... + f(1)] =
2N
