lcm function python code example

Example 1: best way to find lcm of a number python

# Python Program to find the L.C.M. of two input number
#naive method
def compute_lcm(x, y):

   # choose the greater number
   if x > y:
       greater = x
   else:
       greater = y

   while(True):
       if((greater % x == 0) and (greater % y == 0)):
           lcm = greater
           break
       greater += 1

   return lcm

num1 = 54
num2 = 24

print("The L.C.M. is", compute_lcm(num1, num2))

Example 2: 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 3: 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;
