The numbers 1 through 14 (inclusive) are written on the chalkboard. Ms. Q. took the product of 13 of the 14 numbers. How many different products could she get?

14   different  products

 

To see this.....note  that  we  are  omitting   one  of  the  numbers  each  time

 

So.....the products   are

 

14!  / 1  ,    14!  / 2   ,   14! / 3   ........  14! / 12  ,    14!/ 13   ,   14! / 14   =    14 different  products
