Definition: The term "supplest" in mathematics refers to a number that is the sum of its proper divisors. In other words, it's the greatest number that can be divided evenly into any given integer without any remainder. For example, consider the number 6. Its prime factorization is \(2 \times 3\), and since 3 cannot be factored further (it has no divisors), 3 is a proper divisor of 6. Therefore, 6 is the
