How to Simplify Fractions in Python Without Extra Modules

Discover a simple method to simplify fractions in Python using basic arithmetic operations, without relying on external libraries or modules.
---
Simplifying fractions is a common task in mathematical computations and programming. In Python, you can achieve this without needing to import additional modules by leveraging basic arithmetic operations, particularly the concept of the greatest common divisor (GCD).

How Does It Work?

The simplification of fractions involves reducing the numerator and denominator to their smallest possible values while retaining their proportional relationship. This is done by dividing both the numerator and the denominator by their greatest common divisor (GCD).

Steps to Simplify Fractions in Python

To simplify a fraction in Python without using external libraries, follow these straightforward steps:

Identify the Numerator and Denominator: Start by defining the numerator and denominator of your fraction.

Find the Greatest Common Divisor (GCD): Use a simple implementation of the Euclidean algorithm to find the GCD of the numerator and denominator. This algorithm involves a loop where the remainder of the division of the two numbers is calculated until it is zero. The non-zero divisor at this point is the GCD.

Divide by GCD: Once the GCD is determined, divide both the numerator and the denominator by this number to simplify the fraction.

Conclusion

This method provides a simple yet effective way to simplify fractions in Python using only basic arithmetic operations and a few lines of code. By applying the Euclidean algorithm for finding the GCD, you ensure that the fraction is reduced to its simplest form without the need for external assistance from libraries or modules. This approach is ideal for quick computations or educational purposes where using built-in Python capabilities is preferred.

Continue experimenting with this function, applying it to various fractions to see how it consistently reduces them to their simplest forms. It's a practical skill to have in your Python programming toolkit for straightforward mathematical manipulations.
