Hundred Factorial !

 

That ! button on the calculator doesn�t get much attention pre-A level, and here�s one more reason why not � it�s not even useful for questions like this that are all about ! !

 

The Problem :

10!  means 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 and has 2 zeros on the end.

Check this.

With how many zeros does the number 100! end ?
