11. For a positive integer $n$, select several positive divisors of $n$ such that these divisors do not have an integer multiple relationship with each other. Let the maximum number of divisors that can be selected be $f(n)$, then $f\left(2^{2020} \times 2020\right)+f\left(3^{2021} \times 2021\right)+f\left(5^{2022} \times 2022\right)=$ $\qquad$ .
