std::gcd

| template< class M, class N > constexpr std::common_type_t<M, N> gcd( M m, N n ); |
(since C++17) | |
Computes the greatest common divisor of the integers 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.
