Notes:

There are negative factors and multiples as well
It is a Composite Number when it can be divided exactly by a whole number other than itself.
We are only interested in dividing by whole numbers other than the number itself, when the only two factors of a number are 1 and the number then it is a Prime Number
We are only dealing with whole numbers here! We are not going to cut things into halves or quarters.
Any whole number greater than 1 is either Prime or Composite
