WebJun 27, 2024 · The simple algorithm to find the LCM is an iterative approach that makes use of a few fundamental properties of LCM of two numbers. Firstly, we know that the LCM of any number with zero is zero itself. So, we can make an early exit from the procedure whenever either of the given integers is 0. WebNow, this is one way to find the least common multiple. Literally just look at the multiples of each of the number and then see what the smallest multiple they have is in …
WebGiven two numbers, their LCM is the least (that is, the smallest) common (that is, shared) multiple of those two numbers. For instance, given the two numbers 4 and 5, their LCM is the smallest number that includes each of 4 and 5 as factors; in this example, the LCM is 20.
