std::lcm (3) - Linux Man Pages

std::lcm: std::lcm

NAME

std::lcm - std::lcm

Synopsis


Defined in header <numeric>
template< class M, class N> (since C++17)
constexpr std::common_type_t<M, N> lcm(M m, N n);


Computes the least common multiple of the integers m and n.

Parameters


m, n - integer values

Return value


If either m or n is zero, returns zero. Otherwise, returns the least common multiple of |m| and |n|.


Remarks


If either M or N is not an integer type, or if either is (possibly cv-qualified) bool, the program is ill-formed.
The behavior is undefined if |m|, |n|, or the least common multiple of |m| and |n| is not representable as a value of type std::common_type_t<M, N>.

Exceptions


Throws no exceptions.
