The function GCD returns the greatest common divisor of one or more Numbers.

This function takes a Number or Numbers as input. It returns the greatest common divisor as a Number output.

### Declaration

``````GCD(first_number, second_number, nth_number, ...) -> greatest_common_divisor
``````

### Parameters

first_number, second_number, nth_number (type: at least one `Number`)
The numbers to compute the greatest common divisor for.

### Return Values

greatest_common_divisor (type: `Number`)
The greatest common divisor

### Examples

The numbers six, nine, and 15 are all divisible by the number three.

``````GCD(6, 9, 15) -> 3
``````

The numbers five, ten, and 15 are all divisible by the number five.

``````GCD(5, 10, 15) -> 5
``````

While the numbers 15, 30, and 45 are all divisible by both three and five, the largest divisor is 15.

``````GCD(15, 30, 45) -> 15
``````

Between the numbers two, three, and four, the largest common divisor is one, as any number is divisible by one.

``````GCD(2, 3, 4) -> 1
``````

The greatest common divisor of the number 15 is 15, as any number is divisible by itself.

``````GCD(15) -> 15
``````
