Solution in JavaScript (judge verdict: Accepted)

        'use strict';
        (function(stdin) {
          var inputs  = stdin.toString().split(' ').map(Number);
          var a = inputs[0];
          var b = inputs[1];
          var c = inputs[2];

          // console.log(a,b,c);
          var count = 0;
          for (var i = a; i < b + 1; i++){
            if(c % i === 0){
                count++;
            }
        }
        console.log(count);

    }(require('fs').readFileSync('/dev/stdin', 'utf8')));
