Interestingly, David Radcliffe of the University of Wisconsin-Milwaukee Math Department has determined the number of trailing zeros of the Leviathan number. To solve this problem, it suffices to determine the number of factors of five among all the numbers between 1 to 10 . For example, if a number is divisible by 5 but not... 

Thus, David Radcliffe says, 10 ends in 2.5 x 10 - r zeros, where r is between 1 and 1,000. He used a software package called MAPLE (University of Waterloo), which supports high-precision arithmetic, to determine the exact value of r, and finds the number of trailing zeros to be 2.5 x 10 - 143.
