| The boost::math::gcd function template returns the greatest common (nonnegative) |
| divisor of the two integers passed to it. The boost::math::lcm function template |
| returns the least common (nonnegative) multiple of the two integers passed |
| to it. The function templates are parameterized on the function arguments' |
| IntegerType, which is also the return type. Internally, these function templates |
| use an object of the corresponding version of the gcd_evaluator and lcm_evaluator |
| class templates, respectively. |
