This publication establishes a few statements about divisibility and then to manipulating remainders. It is then followed by a discussion on how to know more about a finite cyclic group from knowing divisors of its size. It is a three-page publication aimed at improving the ability to manipulate divisors algebraically and at introducing the reader to the most basic type of group structure: finite cyclic groups.
