## INFORMATION

### LCM CAKE METHOD

The least common multiple (LCM) of two positive whole numbers is the smallest number that is divisible by these numbers. The least common multiple of a set of numbers can be found by using the upside-down cake method (or the ladder method).

In this method, we apply the same algorithm as GCF. To calculate LCM, we multiply all prime numbers on the left and the leftovers on the right.
