title: Multiplying all numbers in the output of a loop
body: <p>I am trying to create an algorithm in Python that takes an input and prints the multiple of all the numbers less than it.
  example:  input ; 3
            output ; 1*2*3 = 6.</p>
  
  <p>example2: input ; 15
            output ; 1*2*3*4*5*6*7*8*9*10*11*12*13*14*15 = 1,307,674,368,000.</p>
