Divisor (of an Integer)

Divisor (of an Integer)
A number that divides the integer exactly (no remainder).
In other words the division works perfectly with no fractions involved.

Example: 3 is a divisor of 12, because 12/3 = 4 exactly

But 5 is NOT a divisor of 12, because 12/5 = 2 with a remainder of 2

And the divisor must itself be an integer (no fractional part).

Note: a divisor is also a factor of the original integer.
