I was able to get to this number: 1 048 576 by using base 4 and making each finger a different “10” s place using each finger segment and the tip of the palm below it but you have to keep track of how many of each order of magnitude you have by yourself. Alternatively, just use a piece of paper.
You can count up to 99 with your hands if you use them like a Japanese abacus.
Up to 1023 if you use binary!
