## Steps to calculate GCD/HCF by Finding Largest Common Factors Method

This method is simple and easy to for beginners. In this method we have to find the factors of each provided
numbers. The factor is the number that can completely divide the provided number. These factors
can be start from 1 (One) upto the number itself. By default 1 is common dividing number and factor, so that if any other factor from
the numbers will not match the **GCD will be 1**.

There are some steps to be followed for the calculation of HCF or GCD by using greatest common factor.

- From start divide and collect or write down each divisor of given numbers. Means write down factors.
- Start dividing every number from 1 to itself means N.
- List factors of each numbers align them vertically.
- Circle or highlight if there are common factors from all these numbers
- In last step identify the greatest number, This number is the GCD.

### Example

### GCD Practice Questions

Some of the important questions that can be solved as practice are as.

- what will GCD of 33, 55 using highest common factor method
