inbuilt libraries for finding lcm in python code example

Example 1: lcm math python library

from math import gcd
def lcm(a,b):
  return a*b/(gcd(a,b))
print(lcm(12,70))
//output: 420

Example 2: python find lcm

def lcm(a, b):
        i = 1
        if a > b:
                c = a
                d = b
        else:
                c = b
                d = a
        while True:
                if ((c * i) / d).is_integer():
                        return c * i
                i += 1;
