torch.gcd#

torch.gcd(input,other,*,out=None)→Tensor#

Computes the element-wise greatest common divisor (GCD) ofinput andother.

Bothinput andother must have integer types.

Note

This defines$gcd(0,0)=0$gcd(0,0)=0.

Parameters

• input (Tensor) – the input tensor.

• other (Tensor) – the second input tensor

Keyword Arguments

out (Tensor,optional) – the output tensor.

Example:

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