numpy.lcm(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'lcm'>

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

Parameters:
x1, x2 : array_like, int

Arrays of values

Returns:
y : ndarray or scalar

The lowest common multiple of the absolute value of the inputs This is a scalar if both x1 and x2 are scalars.
