torch.lcm¶

torch.lcm(input, other, *, out=None) → Tensor¶

Computes the element-wise least common multiple (LCM) of input and other.

Both input and other must have integer types.

Note

This defines $lcm(0, 0) = 0$ and $lcm(0, a) = 0$ .

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.lcm(a, b)
tensor([15, 20, 15])
>>> c = torch.tensor([3])
>>> torch.lcm(a, c)
tensor([15, 30, 15])
