Answers for "The least common multiple (LCM) of a set of positive integers is the smallest positive integer which is divisible by all the numbers in the set. For example, the LCM of 5, 7 and 15 is 105."

get the least common multiple (LCM) of two positive integers

def lcm(x, y):
   if x > y:
       z = x
   else:
       z = y

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

   return lcm
print(lcm(4, 6))
print(lcm(15, 17))
