Greatest Common Factors, Least Common Multiples, and Coprimality

In what follows…

We will be discussing some ideas that you may have learned in high school or perhaps earlier, namely that of greatest common divisors and least common multiples. We will also discuss how one can find greatest common divisors and least common multiples using prime factorizations.
