100! cannot be found on your calculator because it is more than 10 raised to the power of 100. It can be split into 60! * 100nPr40, both numbers less than 10 to the 100th power. Find these values and multiply them together by hand to find 100!

60! = 8.320987113 * 10^81

100 nPr 40 = 1.121576253 * 10^76

Multiplying the significands together we get 9.332621547...

10^81 * 10^76 = 10^(81+76) = 10^157

The full answer with a significand as large as we can get on our calculator is

100! = 9.332621547 * 10^157Post a Comment
