To determine the LCM, we'd have to know the value of x. To determine x, we'd have to know the LCM.
If x = 1, the LCM is 60. If x = 7, the LCM is 420. If x = 120, the LCM is 120.
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.
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.
You need at least two numbers to find an LCM.
No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
The LCM of this number is itself. To find the LCM requires two or more numbers.
