## Steps to calculate GCD/HCF using Repeated Division Method

There are multiple methods to calculate the value of greatest common divisor, One of the famous technique is repeated division. In this technique we will follow the following steps

- Start dividing each provided number from smallest prime number.
- Repeat the step 1 until there is not a single prime number that can completely divide each and every number from the list.
- After this multiply each divisor that will the
*GCD*
