Divisor (of an Integer)
A number that divides the integer evenly (no remainder).
Example: 3 is a divisor of 12, because 12/3 = 4
But 5 is NOT a divisor of 12, because 12/5 = 2 with a remainder of 2
The divisor must also be an integer (no fractional part).
A divisor is also a factor of the original integer.
