# gcd

Returns the greatest common deviser of the set `x`.

## Syntax

g = gcd(x1,x2,...)

[g,v1,...] = gcd(x1,x2,...)

## Inputs

`x1,x2,...`- The elements to find the greatest common divisor of.

## Outputs

- g
- The greatest common divisor of the set.
- v1,...
- Vectors containing integers that, when multiplied by the corresponding x elements and summed up, are equal to the greatest common divisor g.

## Example

Simple gcd example:

`gcd([20 44], [8 11])`

```
ans = [Matrix] 1 x 2
4 11
```

Simple gcd example:

`[g,v1]=gcd([20 44], [8 11])`

```
g = [Matrix] 1 x 2
4 11
v1 = [Matrix] 1 x 2
1 0
```
