what is answer for perfect number????????????????..

Answer / david uwihoreye

Perfect number is a positive number which sum of all
positive divisors excluding that number is equal to that
number. For example 6 is perfect number since divisor of 6
are 1, 2 and 3. Sum of its divisor is
1 + 2+ 3 =6

Note: 6 is the smallest perfect number.

Next perfect number is 28 since 1+ 2 + 4 + 7 + 14 = 28
Some more perfect numbers: 496, 8128
