Simple PHP Challenge (3) by elvis10ten(m): 5:17pm On Jul 15, 2013 |
Write a program that prints the gcf(greatest common factor, that is the greatest number in the common factor of the numbers) of two numbers, If there is no gcf return "1 as the highest gcf". Example the gcf of 15 and 30 is 15, the gcf of 10 and 3 is 1. RULES 1)Run your code on www.ideone.com or post it here if you can't. 2)The shortest a fastest code wins. 3)Your code should be robust and work with any cpu. 4)Your code should be able to run properly on a poor cpu/hardware. Good luck |

//first number $number = array($i,$j,) //Determine the lowest of the numbers asort($number); //Lowest of the numbers $lower_limit = $number[0]; //get all the factors of all the numbers, For($g=0; $g<=$lower_limit; $g++){ For($h=0;$h<=count($number)-1;$h++){ If(fmod($number[$h],$g) == 0){ $factors[$number[$h]][] = $number[$h]/$g; } } } // all common factors $c_factor = array_intersect($factors[0],$factors[1]); //highest common factor $g_c_factor = max($c_factor); echo $g_c_factor; |

Z8:Where is your <?php and ?>. I didn't really look at your code tho, i just noticed those at first. Please correct and try again |

Judinho59: http://ideone.com/vyBw4vpurely wrong solution. Your code will only work with some gcf and not all, so it isn't robust. The rule states so. Here is your solution at work http://ideone.com/dofcYOfunction phpChallenge($int1,$int2){ |
