hcf and lcm in python code example

Example 1: 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 2: python code for gcd of two numbers

# Function to find HCF the Using Euclidian algorithm
def compute_hcf(x, y):
   while(y):
       x, y = y, x % y
   return x

hcf = compute_hcf(300, 400)
print("The HCF is", hcf)

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))
