They were discovered to make calculations, especially multiplication and division, much easier. When they were "invented", there were co calculators of any sort. People did ALL their calculations by pen and paper. This was more than 300 years ago.
As a means of calculation, use of logarithms largely died out around 45 years ago when the first pocket calculators appeared.
Now, their main use comes about because of their relationship with the exponential function.
If \(y = \exp(x) \equiv e^{x}, \text{ then } \ln(y) = x,\)
where ln(y) is the natural logarithm of y.
They crop up naturally in integral calculus, the indefinite integral of 1/x wrt x is ln(x) + C, where C is a constant.
