template< class M, class N> constexpr std::common_type_t<M, N> lcm(M m, N n); | (since C++17) |
Computes the least common multiple of the integers m and n.
| m, n | - | integer values |
If either m or n is zero, returns zero. Otherwise, return the least common multiple of |m| and |n|.
If either M or N is not an integer type, the program is ill-formed.
The behavior is undefined if.
|m| is not representable as a value of type M; or |n| is not representable as a value of type N; or |m| and |n| is not representable as a value of type std::common_type_t<M,N>. Throws no exceptions.
| (C++17)
| constexpr function template returning the greatest common divisor of two integers (function template) |
