Determining Period (T) and fundamental frequency (Omega)

Questions
1

Hi;

Does Mathematica have a function that will calculate the Period (T) and fundamental frequency (Omega) given a series of frequencies such as (2, 3.5, 5) or (12, 27, 51) - for a couple of examples?

If a specific function does not exist, what is the recommended method to calculate these values using Mathematica other than using regular math methods?

Thanks,

Mitch Sandlin

Hint:

LCM[1/2,2/7,1/5]

Think how that relates to your first example and what the result of that means.

That should be enough.
