Below is the python code to find H.C.F. and L.C.M. of two numbers using functions.
LCM= Product of the numbers/HCF
def HCF(n1,n2):
a,b=n1,n2
p=a*b
for i in range(1,p):
if (a%i==0) and (b%i==0):
gcd=i
return gcd
# main program
m=int(input("Enter first number:"))
n=int(input("Enter second number:"))
k=HCF(m,n)
lcm=int((m*n)/k)
print("The GCD/HCF of two numbers=",k)
print("The LCM of two numbers=",lcm)
Output
Enter first number:65
Enter second number:7
The GCD/HCF of two numbers= 1
The LCM of two numbers= 455
