Question 1 : Find the number of zeroes in 155! Solution: Multiplication of 2×5 results into 10. So number of zeroes depend on the number of pairs of 2 and 5. In any factorial, number of 5’s is lesser than the number of 2’s. So, we need to count the maximum power of 5 in 155! [155/5] + [155/5 2] + [155/5 3] =31 + 6 +1 =38 Hence, number of ...
