What is the greatest integer m for which the number 50!/10^m is an integer? Choose the correct choice from the following
A) 5 B) 8 C) 10 D) 11 E) 12
As for 50!/10^m, the greatest value of m will be obtained by finding the maximum number of 5s in 50!   The quick process for that (discussed in the link above) is   50/5= 
<gadget id="calculator">50/5</gadget>
<output>10</output>
10   10/5= 
<gadget id="calculator">10/5</gadget>
<output>2</output>
2   Total number of 5s is 12. So maximum value of m will also be 12.   Answer (12)
<result>E</result>
