Mathematicians and number enthusiasts have been fascinated for
centuries by the divisors of numbers.  They have noticed that some
numbers like 6 = 1+2+3 and 28 = 1 + 2 + 4 + 7 + 14 are equal to
the sum of all of their factors (not including the number itself).
They have called such numbers PERFECT. If you add up the divisors of a
number like 10 you will find that 1+2+5 = 8.
