This task requires the finding of the greatest common divisor of two integers.
Copied from least common multiple page for the sake of completeness.
#include <boost/math/common_factor.hpp> #include <iostream> int main( ) { std::cout << "The least common multiple of 12 and 18 is " << boost::math::lcm( 12 , 18 ) << " ,\n" << "and the greatest common divisor " << boost::math::gcd( 12 , 18 ) << " !" << std::endl ; return 0 ; }
- Output:
The least common multiple of 12 and 18 is 36 , and the greatest common divisor 6 !
