Develop a library based on the functions that we have considered in this book for computing properties of integers. Include functions for determining whether a given integer is prime; determining whether two integers are relatively prime; computing all the factors of a given integer; computing the greatest common divisor and least common multiple of two integers; Euler's totient function (EXERCISE 2.1.26); and any other functions that you think might be useful. Include overloaded implementations for 1ong values. Create an API, a client that performs stress testing, and clients that solve several of the exercises earlier in this book.
