如何找到一系列数字的LCM？

Question

I want to find the LCM (Least Common Multiple) of the numbers 1 to 20 (1,2,3,4,5,6,7...17,18,19,20). I have tried using math.lcm() and numpy.lcm() but got the following errors with the following code:

#numpy
import numpy as np

answer = np.lcm(range(1,20))
print(answer)

TypeError: lcm() takes from 2 to 3 positional arguments but 1 were given

#math.lcm
from math import lcm

answer = lcm(range(1,20))

ImportError: cannot import name 'lcm' from 'math' (/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/lib-dynload/math.cpython-38-darwin.so)

If it helps at all, I am using Python 3.8

Answer 1

Make sure you are updated to Python 3.9+

I switched to Python 3.10.5 and used:

math.lcm(*range(1,21))

And it worked math.lcm(*range(1,21)) found the Least Common Multiple of the numbers 1-20
