Calculate the LCM of a list of given numbers in Python

This is the best way that I know of :

from math import gcd
a = [100, 200, 150]   #will work for an int array of any length
lcm = 1
for i in a:
    lcm = lcm*i//gcd(lcm, i)
print(lcm)

Hope this helps. All queries, contributions and comments are welcome 🙂
