That is because - for example - some calculations are easier in polar coordinates, and some are easier in rectangular coordinates. For example, complex numbers are easier to add and subtract in rectangular coordinates, and easier to multiply and divide in polar coordinates.
Finding the LCM helps you add and subtract fractions accurately.
It allows you to add and subtract the fractions with greater ease.
