lcm

fntypeof(Unqual!(T).init % Unqual!(U).init) lcm(T, U)(T a, U b) if (isIntegral!T && isIntegral!U)

Computes the least common multiple of a and b. Arguments are the same as gcd .

The least common multiple of the given arguments.

auto lcm(T)(T a,  T b) if (!isIntegral!T &&
         is(typeof(T.init %  T.init))  &&
         is(typeof(T.init ==  0 ||  T.init >  0)))
