Etymology

Origin of divisor

1425–75; late Middle English < Latin dīvīsor, one who divides, equivalent to dīvīd- (variant stem of dīvidere to divide ) + -tor -tor

Explanation

In math, the number you're dividing by is called the divisor. In the equation 24 ÷ 6 = 4, the divisor is 6. Often math teachers use the word divisor simply to mean any number by which you're dividing another number, whether it divides evenly or leaves a remainder. An alternate definition is "a number that divides into another without a remainder." If you need to find the greatest common divisor of several numbers, you're looking for the largest number that divides evenly, with no remainder, into all of them.
