## Steps to calculate GCD/HCF using Euclidean Algorithm

Euclidean Algorithm is also quick and easy way for finding GCD/HCF. This method is used for calculating GCD of only two numbers. If we provide more that two numbers for calculation then this system will take only minimum and maximum numbers.

The following steps are used for calculating GCD

- First of all find the minimum number out of the given numbers
- Then divide the maximum number by minimum number
- If the remainder of the above division is not equal to zero
- It mean minimum number is not completely dividing the maximum number.
- Then divide the minimum number by the remainder of above steps
- Repeat the process until the remainder of numbers is not zero.
