Return the greatest common divisor and lowest common multiple in Numpy
To return the greatest common divisor, use the numpy.gcd() method in Python Numpy. The parameters are arrays of values. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).
To return the lowest common multiple, use the numpy.lcm() method in Python Numpy. The greatest common divisor of the absolute value of the inputs This is a scalar if both x1 and x2 are scalars.
Steps
At first, import the required library −
import numpy as np
To return the greatest common divisor, use the numpy.gcd() method in Python Numpy. The parameters are arrays of values. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output) −
print("LCM...
", np.lcm(15, 30))
print("LCM...
", np.lcm(10, 50))
print("LCM...
", np.lcm.reduce([6, 18, 30]))To return the lowest common multiple, use the numpy.lcm() method in Python Numpy −
print("GCD...
", np.gcd(15, 30))
print("GCD...
", np.gcd(10, 50))
print("GCD...
", np.gcd.reduce([25, 75, 100, 125]))Example
import numpy as np
# To returns the greatest common divisor, use the numpy.gcd() method in Python Numpy
# The parameters are arrays of values.
# If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).
print("LCM...
", np.lcm(15, 30))
print("LCM...
", np.lcm(10, 50))
print("LCM...
", np.lcm.reduce([6, 18, 30]))
# To returns the lowest common multiple, use the numpy.lcm() method in Python Numpy
print("GCD...
", np.gcd(15, 30))
print("GCD...
", np.gcd(10, 50))
print("GCD...
", np.gcd.reduce([25, 75, 100, 125]))Output
LCM... 30 LCM... 50 LCM... 90 GCD... 15 GCD... 10 GCD... 25
