Web28 jul. 2024 · Observe that each trailing zero means a factor of 10, so we just need the lesser count of 2s or 5s in the prime factors of the factorial (which is the count of all 2s … Web28 jul. 2024 · Better idea. A trailing zero means divisibility by 10, you got it right; but the next step is to realize that 10 = 2 ∗ 5, so you need just count the number of factors of 2 and 5 in a factorial, not to calculate the factorial itself. Any factorial have much more even factors then divisible by 5, so we can just count factors of 5.

Web28 mrt. 2016 · You need to find how many powers of ten in a factorial, not calculate a factorial and then find the number of trailing zeros. The simplest solution is to count the number of powers of five. The reason you only need to count powers of five is that there is plenty of even numbers in between then to make a 10. WebYou can get a very good estimate by (a) calculating the number of powers of ten in the factorial, (b) estimating the total number of decimal digits (using Stirling's approximation), and (c) assuming all digits except the trailing zeroes are equally likely to have any value.
