I am a mathematics lecturer at the University of Washington.

I received my Ph.D. in 1997 under the direction of Peter Elliott. My dissertation was in analytic number theory.

comment This is question 3.3 from Alan Karr's Probability
Welcome to math.SE: since you are new, I wanted to let you know a few things about the site. In order to get the best possible answers, it is helpful if you say in what context you encountered the problem, and what your thoughts on it are; this will prevent people from telling you things you already know, and help them give their answers at the right level. If this is homework, please add the homework tag; people will still help, so don't worry.

comment An number theoretic inequality
I think a good approach would be to show that the lhs is less than, say, $\frac{1}{2}e^n$ (you might use Stirling's formula for the factorial part) while the rhs is greater than, say, $0.9e^n$ for $n$ greater than some bound (the prime number theorem implies $\log(\textrm{lcm}(1,2,\dots,n))/n$ is asymptotic to 1 as $n$ tends to infinity).

Why do you want to prove this? Where did you encounter this problem?

comment Is 292229292292 the longest 29-smooth number made of 2's and 9's?
@UmbertoP. It means the number has no prime factor greater than 29. See en.wikipedia.org/wiki/Smooth_number
