Default Not the largest prime

My apologies, I dont know my way around this forum. Could someone re-direct this 'post' to the right place/ forum or do what is necessary? Or even answer it if there is a well known answer? Presumably the answer will get bigger as more primes are discovered

This is not a Mersenne question.

What is the largest prime number for which all smaller primes are known?

And secondly given the well known proof that there are an infinite number of primes, how many digits are there in the answer if all primes less than or equal to 'my' prime are multiplied together?
