A Duffinian number is a composite number that has no prime factors in common with the sum of its divisors, denoted σ(n). The sum of divisors, σ(n), includes all positive divisors of a number n, including 1 and n itself. A number is called Duffinian if it is relatively prime to the sum of its divisors, meaning they share no common prime factors. For example, 16 is Duffinian number because the sum of its divisors shares no prime factors with the number itself. This property helps to highlight the unique relationship between a number and the sum of its divisors.
