Every multiple of 5 contributes one 0.
Multiples of 52 = 25 contribute a second 0;
Multiples of 53 = 125 contribute a third 0;
Multiples of 54 = 625 contribute a fourth 0.
This suggests there are 501 zeros.

My calculation gave me 2963 hopefully that is right... * * * * * I suggest 501.
122 zeros.
To calculate the number of zeros in a factorial number, we need to determine the number of factors of 5 in the factorial. In this case, we are looking at 10 to the power of 10 factorial. The number of factors of 5 in 10! is 2 (from 5 and 10). Therefore, the number of zeros in 10 to the power of 10 factorial would be 2.
Two!
20! is 2,432,902,008,176,640,000, so there are four consecutive zeroes at the end of 20!
