A perfect number is a positive integer that is equal to the sum of its proper divisors, excluding itself. In other words, if \\( n \\) is a perfect number, then the sum of its divisors (excluding \\( n \\)) equals \\( n \\). For example: - The smallest perfect number is 6. Its divisors are 1, 2, and 3.
