MathsLogical Number Problem - 25 March

According to number theory of mathematics , a perfect number is a positive integer that is equal to the sum of its positive divisors excluding the number itself.
For example :
6 => 1+2+3
28 =>1+2+4+7+14

I know one more number that is a perfect number and contains not more than 2 digits (i.e 496 won't be consider as it contains 3 digits).

Find the number ?

  4. A perfect number is a +ve integer that is equal to the sum of all of its +ve divisors excluding the number itself.
    then,12 is not equal to its +ve divisors,i.e.,1+2+3+4+6.
