Method 1: List the multiples
Method 2: Prime factorization
Avoidance. It is impossible to find the LCM of a single number. You need at least two.
It is: 30
The LCM is 30.
Just write a method or function that calculates the LCM for two numbers at a time. Then calculate the LCM for the first two numbers, get the LCM of the result with the third number, etc.Just write a method or function that calculates the LCM for two numbers at a time.

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.
The LCM is 10.
You need at least two numbers to find an LCM.
The LCM of two consecutive even numbers is their product divided by two.
Two or more numbers are normally needed to find the LCM
You need at least two numbers to find an LCM.
This number's LCM is itself, as LCM requires two or more numbers.
LCM involves two or more numbers. The LCM of this number is itself.
