# Seperable Integers

**Number Theory**Level 4

*two-separable* if it can be represented as the product of two positive integers that differ by two. (For example, since \(8=2\cdot 4\), \(8\) is two-separable.) Similarly, an integer is said to be *nine-separable* if it can be represented as the product of two positive integers that differ by \(9\). What is the sum of all positive integers that are both two-separable and nine-separable?
