A number is called a perfect number if it equals the sum of all its factors except itself. for instance , 6 is a perfect number because its factors are 1,2,3 and 6 and 1 + 2 + 3 = 6 .What is the next greater perfect number ?

Answer 1

28
Equivalently, the number 6 is equal to half the sum of all its positive divisors: ( 1 + 2 + 3 + 6 ) / 2 = 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. This is followed by the perfect numbers
(1+2+4+7+14+28)/2
56 / 2 = 28

Answer 2

1+2+3+6 then 1+2=3 then 3+3=6 final answer 6+6 = 12 as the next perfect number
