If \(a_1,a_2,\cdots,a_{37}>0\)

\[\large\left(\sum\limits_{i=1}^{37}a_i\right)\large\left(\sum\limits_{i=1}^{37}\dfrac{1}{a_i}\right) \ge K\]

Find \(K\).

\(\)

**Bonus**:

- Try with power mean inequality
- For \(\displaystyle \left(\sum_{i=1}^n a_i\right)\left(\sum_{i=1}^n \dfrac{1}{a_i}\right) \ge X\), find \(X\).
