How to find gcd of very large numbers represented in string

#1

given gcd(string st1,string st2) how to find gcd ?

@sahazeer123 you can first convert string to integer (or long long) then you can find gcd, you can also find gcd if atleast one of the numbers is within 10^18, otherwise you can use python or java to handle big integers with same euclidean algorithm.
