## Asymptotic estimation of $A_n$

Let $$A_n$$ represent the number of integers that can be written as the product of two element of $$[[1,n]]$$.

I am looking for an asymptotic estimation of $$A_n$$.

First, I think it’s a good start to look at the exponent $$\alpha$$ such that :

$$A_n = o(n^\alpha)$$

I think we have : $$2 < alpha$$. To prove this lower bound we use the fact that the number of primer numbers $$\leq n$$ is about $$\frac{n}{\log n}$$. Hence we have the trivial lower bound (assuming $$n$$ is big enough) :

$$\frac{n}{\log n} \cdot \binom{ E(\frac{n}{\log n})}{2} = o(n^3)$$

Now is it possible to get a good asymptotic for $$A_n$$ and not just this lower bound ? Is what I’ve done so far correct ?

Thank you !
