Published by admin under Technical on August 10, 2008

One day, when i was chatting with my friend i suddenly received one message from my sister, in that she asked the big question what is a perfect number. I stunned because i did not hear that word any where, i thought this is the time to learn a new thing. I want to share what i learned about the perfect number. The perfect number is the one, when its positive divisors are sum up to get the same number. In other words the sum of a number and its positive divisors when divided by 2 give the same number is called the perfect number. You will clear by the following example, consider the number 6. Its divisors are 1,2,3, if we sum these numbers , that is 1+2+3=6, give the number 6. The second perfect number is 28. I left the working part to you. Then if you know more share that with me.
