numpy.gcd

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

Returns the greatest common divisor of |x1| and |x2|

Parameters

x1, x2array_like, 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

yndarray or scalar

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

lcm

The lowest common multiple

Examples

>>>

>>> np.gcd(12, 20)

>>> np.gcd.reduce([15, 25, 35])
5
>>> np.gcd(np.arange(6), 20)
array([20,  1,  2,  1,  4,  5])
