output_description: Print the number of divisors in a line.
input_description: Three integers a, b and c are given in a line separated by a single space.
attempt: i = input().split()
  i = [int(x) for x in i]
  c = [1 for x in range(i[0], i[1] + 1) if i[2] % x == 0]
  print(sum(c))
  
problem_description: How Many Divisors?
