Well, isn't that a happy little question! When you calculate the factorial of a number, you multiply that number by all the positive integers less than it. The last digit of factorial 99 is 0, because there are lots of factors of 2 and 5 in the multiplication, creating zeros at the end. Just imagine all those zeros as little trees in a beautiful forest of numbers!

242 zeros.
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.
There are 24 trailing zeros in 100 factorial.
18 factorial is equal to 6402373705728000 - with three consecutive zeroes at the end.
75 factorial = 75! = 2.48091408 x 10109
My calculation gave me 2963 hopefully that is right... * * * * * I suggest 501.
Seven.
Five.
There are 9 zeros in 75 billion in the US and current UK short scale. This is 75,000,000,000. There are 12 zeros in 75 billion in the older UK long scale. This is 75,000,000,000,000.
75,000,000 = 75 million and so there are six of them
