A Harmonic Divisor number is a positive integer n for which the harmonic mean of all its divisors is an integer. In other words, the product n * τ(n) / σ(n) is an integer, where τ(n) is the number of divisors of n, and σ(n) is the sum of its divisors. To check if a number is a Harmonic Divisor number, verify if its harmonic mean of divisors is an integer. For example, 28 is Harmonic Divisor number because the harmonic mean of its divisors results in an integer.
