Divisor (of an integer)

A number that divides the integer exactly (no remainder).

In other words the division works perfectly with no fractions or remainders involved.

Examples:
• 3 is a divisor of 12, because 12 ÷ 3 = 4 exactly
• 4 is a divisor of 12, because 12 ÷ 4 = 3 exactly
• 5 is not a divisor of 12, because 12 ÷ 5 = 2 with a remainder of 2


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