👉 In mathematics, a paragnathous number is a positive integer that is equal to the sum of its proper divisors. This means that it can be expressed as n = d1 + d2 + ... + dn-1 + n, where each d is a divisor of n and 1 ≤ d ≤ n. For instance, 6 is a paragnathous number because 6 = 1 + 2 + 3. Similarly, the sum of all divisors of
