Returns the greatest common divisor of two or more integers. The greatest common divisor is the largest integer that divides both number1 and number2 without a remainder.

## Syntax

``````GCD(number1, [number2], ...)
``````

#### Parameters

TermDefinition
number1, number2, ...Number1 is required, subsequent numbers are optional. 1 to 255 values. If any value is not an integer, it is truncated.

## Return Value

The greatest common divisor of two or more integers.

## Remarks

If any argument is nonnumeric, GCD returns the #VALUE! error value.

If any argument is less than zero, GCD returns the #NUM! error value.

One divides any value evenly.

A prime number has only itself and one as even divisors.

If a parameter to GCD is >=2^53, GCD returns the #NUM! error value.

## Example

=GCD(5, 2)Greatest common divisor of 5 and 2.1
=GCD(24, 36)Greatest common divisor of 24 and 36.12
=GCD(7, 1)Greatest common divisor of 7 and 1.1
