How many trailing zeroes are there in 100! (100 factorial) ?

SOLUTION : To make a 10, we need one 5 and one 2 to be multiplied and become 10. Because 10 cannot be prime factorized in amy other way. In prime factorization of 100 factorial, there are 97 times 2 will come and 24 times 5 will come.

To make 10, we need one 5 and one 2 to be multiplied.

With 97 2's and 24 5's, we can make 24 10's. So, 24 is the answer.
