If you use methods based on prime factors, it is the same whether you have 2, 3, or more numbers: find all the factors that occur in any of your numbers. If you use a method based on Euclid's Algorithm (that is, lcm(a, b) = a x b / gcf(a, b), where you find the gcf with Euclid's Algorithm), then you can find the lcm for two numbers at a time. For example, to get the lcm of four numbers, find the lcm of the first two, then the lcm of the result and the third number, than the lcm of the result and the fourth number.

A x B/HCF(a,b)

it is a method in mathematics that helps to find out LCM

Two or more numbers are needed to find the LCM

No matter what method you use, you need at least two numbers to find an LCM.

Find the LCM of the first two numbers and then find the LCM of that number and the third one. That answer will be the LCM of all three.
