I want a c code of GCD of more than 3 no.?

Like GCD(a,b,c,d,f)


Here a=10,b=12,c=14,d=16 and so on.

I want a c code of GCD of more than 3 no.?
You could, in theory, factor all of the numbers and multiply


their common elements to find the GCD of all numbers.


It wouldn't be very efficient, though.





Instead, you should start with a good implementation of


the Euclidean algorithm for two numbers, GCD(a,b).


Then you can synthesize the function you asked for


using the identity:





    gcd(a, b, c) = gcd(gcd(a, b), c)
