A perfect number is defined as a number the sum of whose divisors (excluding the number itself, but including 1) is equal to the number itself. 6 is the lowest perfect number. find the second lowest number.
a)12
b)14
c)28
d)496

• The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and 1 + 2 + 3 = 6. 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 496 and 8128

• 28 is divisible by 2,4,7 and 14. the sum of the divisors of 28 including 1 is 1+2+4+7+14 = 28. So acc to defn 28 is a perfect no.
