LCM CAKE METHOD

So as to compute the LCM of three numbers, we can use the cake (ladder) method.

In this method, after we write the given numbers to the right, we seek for the prime numbers that divide all three numbers, exactly. Once we find such a prime number, we write it to the LHS, divide the numbers on the right by this prime number and write the quotients to a new layer. We continue this algorithm until no prime number that divides all three numbers is left.

Next, we search for the prime numbers that divide two of the numbers on the right. If we find such a prime number, we divide the pair of numbers that are divisible by the prime number and write the quotients to a new layer. We bring the third number down without making the division.

We continue searching for such prime numbers until all pairs are relatively prime. Then we multiply the prime numbers on the LHS of the cake and the leftovers in order to find the LCM.
