what is the greatest integer m for which the number 50 ! / 10 ^ m is an integer ?
"as for 50 ! / 10 ^ m , the greatest value of m will be obtained by finding the maximum number of 5 s in 50 ! the quick process for that ( discussed in the link above ) is 50 / 5 = 10 10 / 5 = 2 total number of 5 s is 12 . so maximum value of m will also be 12 . answer ( e )"
floor(divide(50, divide(10, const_2)))
