Number k is a proper divisor of number n if k < n and k is a divisor of n. For example, 3 is a proper divisor of 6 and 5 is a proper divisor of 15. The number 1 is a proper divisor of all numbers.
A number n is perfect if the sum of the proper divisors of n is n. For example, the proper divisors of 6 are 1, 2 and 3. Since 1+2+3 = 6, 6 is a perfect number. Similarly, the proper divisors of 28 are 1, 2, 4, 7, and 14. Since 1+2+4+7+14 = 28, 28 is a perfect number.
