std::experimental::gcd - cppreference.com

Merged into ISO C++ The functionality described on this page was merged into the mainline ISO C++ standard as of 6/2016, see std::gcd (since C++17)

template< class M, class N>
constexpr std::common_type_t<M, N> gcd( M m, N n );

Computes the greatest common divisor of the integers m and n.

Parameters

Return value

If both m and n are zero, returns zero. Otherwise, returns the greatest common divisor of |m| and |n|.

If either M or N is not an integer type, or if either is (possibly cv-qualified) bool, the program is ill-formed.

If either |m| or |n| is not representable as a value of type std::common_type_t<M, N>, the behavior is undefined.

Exceptions

Throws no exceptions.
