"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. " - Number of zeros in 99 factorial
