Comments

The factorial of 10^666, called the Leviathan number by Clifford A. Pickover, is 10^(6.655657055...*10^668), which means that it has approximately 6.656*10^668 decimal digits. The number of trailing zeros is Sum_{k=1..952} floor(10^666/5^k) = 25*10^664 - 143. The last nonzero digits are ...708672.
