I need the greatest common divisor between two numbers in the smart contract. I tried:

int gcd = __gcd(num1, num2);

num1 and num2 are two numbers. When the smart contract is compiled, its generating error:

error: use of undeclared identifier '__gcd'

I also tried std::__gcd but no use. It seems EOS doesn't support __gcd. Please help.

You should have #include <numeric> to use std::gcd in your code.
