You can't possibly be this stupid.
"Hyaku" in Japanese is not just hundred but it's used to a mean a lot/shitton. Hyakuju no Kaido is just that: King of the (Many Beasts). It's not that Kaido is literally in charge of 100 beasts.
So "100 times stronger" in Sabaody and now is just an expression meaning way stronger. It's not meant to be a literal figure.
