Perfect numbers

Let me introduce a new subject
Every number can be broken up into factors.The factors can then be added up.In many cases the total will be more than the number under consideration and  similarly in many other cases it will be less.But only in a very very few cases the total will be the same as the number itself.Such numbers are called Perfect numbers.The few examples are 6......,28     ,496      8128   and believe me the next number is 32949336.There is a formula to work out such numbers but I do not wish to burden readers with those calculations.Readers may themselves try and find the same.
