# xarray.ufuncs.lcm

### xarray.ufuncs.lcm *= <xarray.ufuncs._binary_ufunc object>*

xarray specific variant of `numpy.lcm()`. Handles xarray objects by dispatching to the appropriate function for the underlying array type.

Documentation from numpy:

Returns the lowest common multiple of `|x1|` and `|x2|`

* **Parameters:**
  **x1, x2** ([array_like](https://numpy.org/doc/stable/glossary.html#term-array_like), [`int`](https://docs.python.org/3/builtins/functions.html#int)) – Arrays of values.
  If `x1.shape != x2.shape`, they must be broadcastable to a common
  shape (which becomes the shape of the output).
* **Returns:**
  **y** ([`ndarray`](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html#numpy.ndarray) or [scalar](../user-guide/terminology.html.md#term-scalar)) – The lowest common multiple of the absolute value of the inputs
  This is a scalar if both x1 and x2 are scalars.
