# Reduce the fraction to its lowest form

Given two integers **x **and **y **and where x is divisible by y. It can be represented in the form of a fraction **x/y**. The task is to reduce the fraction to its lowest form.**Examples:**

Input :x = 16, y = 10Output :x = 8, y = 5Input :x = 10, y = 8Output :x = 5, y = 4

**Approach:** Both of the values **x** and **y **will be divisible by their greatest common divisor. So if we divide x and y from the gcd(x, y) then x and y can be reduced to its simplest form.

Below is the implementation of the above approach:
