# tensorplay.functional.gcd

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.gcd.html

```python
tensorplay.functional.gcd(input, other, *, out=None) → Tensor
```

Computes the element-wise greatest common divisor (GCD) of input and other.

Both input and other must have integer types.

> **Note**
>
> This defines $gcd(0, 0) = 0$.

Parameters:

- input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

- other ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the second input tensor

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.

Example:

```
>>> a = tensorplay.tensor([5, 10, 15])
>>> b = tensorplay.tensor([3, 4, 5])
>>> tensorplay.gcd(a, b)
tensor([1, 2, 5])
>>> c = tensorplay.tensor([3])
>>> tensorplay.gcd(a, c)
tensor([1, 1, 3])
```
