# GCD

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

Term Definition
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.

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
