Dear bull fighter, I was extremely happy seeing this post, but when I tried to go to these pages, I get the message "Oops! Sorry, that page isn't here." I guess test magic site has been redesigned or something. Can you please update the page links. It will be really very helpful for me and many other novice members.
Thanks.

Q. When dividing 20! by 2^x, what is the maximum value that x can take?

p.n. 20! is 20factorial.

Expln:

20/2 = 10 (record this)
20/4 = 5 (record this)
20/8 = 2 (record this, just take the integer value)
20/16 = 1 (record this, just take the integer value)

Now sum all of them : 10 + 5 +2 +1 = 18. which is the answer.
The idea is to keep dividing by the powers of 2, till the highest power of 2 less than 20, in this case 16....

bullfighter, i didnt get the expln for this one!:(
