Returns the greatest common divisor of two or more integers.


GCD(integer1; integer2; ... integer30)

integer1 to integer30 are up to 30 integers or ranges of integers whose greatest common divisor is to be calculated.
The greatest common divisor (or highest common factor) is the largest positive integer which will divide, without remainder, each of the given integers.


GCD(16; 32; 24)

returns 8, because 8 is the largest number that can divide 16, 24 and 32 without a remainder.


where cells B1, B2, and B3 contain 9, 12, and 6 returns 3.

GCD(3; 5)

returns 1.


GCD will currently produce results with negative and fractional arguments. This has not been a documented feature, and it is planned that from OOo3.0 negative arguments will yield an error and that fractional arguments will be truncated prior to processing, in order to comply with the ODFF standard.
