divisibility - The method of solving for a factor of 90!


If 90!=(90)(89)(88)...(2)(1), then what is the exponent of the highest power of 2 which will divide 90! ?




How would I apply one of the easiest method from Here?




I need help on applying the link to this question.



I do not understand which one explains my case, and how I can solve using the method.



I would appreciate if someone showed how it is applied to this
