How do you calculate the least common multiple of multiple numbers?

So far I've only been able to calculate it between two numbers. But have no idea how to expand it to calculate 3 or more numbers.

So far this is how I did it

LCM = num1 * num2 /  gcd ( num1 , num2 )

With gcd is the function to calculate the greatest common divisor for the numbers. Using euclidean algorithm

But I can't figure out how to calculate it for 3 or more numbers.
