How would you find the most amount of unique rationals summed together, in the form of 1/x, that sum to 1, However your x has to be between 2-2023?

So basically 1/2 + 1/3 + 1/6 = 1 

thats 3 rational numbers

I need to get the most amount of rational numbers that equal to 1 altogether, please let me know if any methods or anything, thanks

$\sum_{i=1}^\infty \dfrac{1}{2^i} = 1$

    That's a great example, even though it does not satisfy x\leq 2023.
