A number by which another is divided; b is the divisor in a / b = c.

The nonzero integer d is a divisor of the integer n if n/d is an integer.

one of two or more integers that can be exactly divided into another integer; "what are the 4 factors of 6?"

the number by which a dividend is divided

An arbitrary number chosen at the starting date of an index to fix the index starting value (i.e. 1000.0). The divisor is also adjusted when capitalisation amendments are made to the constituents of the index in order to allow the index value to remain comparable over time. Without a divisor the index value would change when corporate actions took place and would not reflect the true value of an underlying portfolio based upon the index.

A number that is divided into another number, the dividend. E's

The number by which another number is divided.

The divisor is the number that the dividend is divided by (in long division). The dividend divided by the divisor is the quotient (plus a remainder).

A mathematical quantity used to compute an index. It is initially an arbitrary number that reduces the index value to a small, workable number. Thereafter, the divisor is adjusted for stock splits (price-weighted index) or additional issues of stock (capitalization-weighted index).
