LCM of a number in python code example

Example 1: lcm of n numbers python

# importing the module
import math

# function to calculate LCM
def LCMofArray(a):
  lcm = a[0]
  for i in range(1,len(a)):
    lcm = lcm*a[i]//math.gcd(lcm, a[i])
  return lcm


# array of integers
arr1 = [1,2,3]
arr2 = [2,3,4]
arr3 = [3,4,5]
arr4 = [2,4,6,8]
arr5 = [8,4,12,40,26,28]

print("LCM of arr1 elements:", LCMofArray(arr1))
print("LCM of arr2 elements:", LCMofArray(arr2))
print("LCM of arr3 elements:", LCMofArray(arr3))
print("LCM of arr4 elements:", LCMofArray(arr4))
print("LCM of arr5 elements:", LCMofArray(arr5))

Example 2: lcm python

# Python program to find the L.C.M. of two input number

# This function computes GCD 
def compute_gcd(x, y):

   while(y):
       x, y = y, x % y
   return x

# This function computes LCM
def compute_lcm(x, y):
   lcm = (x*y)//compute_gcd(x,y)
   return lcm

num1 = 54
num2 = 24 

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

Example 3: 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 4: 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;
