Answers.Text: @Ambo100 1:10^90 would suffice to bring the time down to 46 years and is a nice and round number to work with. The questions of what volume would be occupied by the resulting drivetrain and what torque would be needed to drive it, are left as an exercise to the reader :)

Comments.Text: Please edit the question to show what have you tried and where did you get confused. Additionally, if you got to the point of using a calculator, you have probably learned the RPM of the motor, at which point the question is a purely mathematical one, and therefore belongs to another SE site. Nevertheless, I gave below a complete answer according to the "teach a man to fish" philosophy.

  According to [Philo's LEGO motor datasheet](https://www.philohome.com/motors/motorcomp.htm) an unladen PF-M motor rotates with 405 RPM.
  
  One googol is 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 (10^100), so the time it takes for an M motor to go this many rotations is (10^100)/405 minutes.
  
  Ordinary calculators usually take a look at such large numbers and throw their hands up, or can't even display them but luckily we have [WolframAlpha](https://www.wolframalpha.com/input/?i=%281%20googol%20%2F%20405%29%20minute).
  
  This is 4.695x10^91 years, or about 3.4x10^81 times the current age of the universe. (the Universe is about 14 Gigayears old now, in 2021 :) )
