[Wikipedia] "On many handheld scientific and graphing calculators, the highest factorial that can be computed within memory limitations is 69! or 1.711224524 * 10^98." MathBabbler has not checked to see if this is valid information; however, he did notice, via the Google calculator, that 70! equals 1.19785717 * 10^100. Note: 10^100 is a googol (i.e. 1000 duotrigintillion).
