Input

Three integers a, b and c are given in a line separated by a single space.

Output

Print the number of divisors in a line.

Constraints

1 ≤ a, b, c ≤ 10000

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in JavaScript (judge verdict: Accepted)

process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data',function(chunk){


var data = chunk.toString().split(' ').map(Number);

var a = data[0];
var b = data[1];
var c = data[2];
var count = 0;

for(var i = a; i < b+1 ; i++){

if(c % i === 0){
    count++;
  }
 }
console.log(count);
});
