  1. Find the GCD (Greatest Common Divisor) of 12 and 28 which is 4.
  2. Multiply the numbers 12 and 28 together ( 12 * 28 = 336 )
  3. Divide the 336 with 4. (336/4 = 84)

So, the LCM of 12 and 28 is 84.

Now we will find the LCM of above result (84) and third number (43) using the same procedure.

The Result: 3612 is the LCM.
