# What are these numbers trying to do?

Algebra Level 3

Challenge: Try to solve this without using logarithm!

If $$a, b, c, d$$ and $$e$$ are real values that satisfy the system of equations:

$$29^{a} = 31^{b} = 37^{d} = 41^{d} = 1363783^{23}$$

Find the value of $$\frac{1}{a} + \frac{1}{b} + \frac{1}{c} + \frac{1}{d}$$

There is exactly one place in solving this problem when you really need a calculator, but not a scientific one. Round your answer to 5 decimal places.
