## About the calculation of Common divisor(Two numbers)

Enter the two numbers you want to calculate the common divisor and click "calculate common divisor", the number of all common divisor and common divisor of the input value is displayed.

Please enter an integer between 1 and 1,000,000,000,000.

## What is a common factor?

A number that can divide an integer is called a divisor, and a divisor that is common to two or more integers is called a common divisor.

For example, suppose you want to find the common factor of 12 and 18.

The divisors of 12 are 1, 2, 3, 4, 6, and 12, and the divisors of 18 are 1, 2, 3, 6, 9, and 18.

Of these divisors, the common divisors of 12 and 18 are 1, 2, 3, and 6.

## How to calculate a common factor

To calculate common factors, write down the factors of each number and extract the common value.

Example: Calculate the common factor of 24 and 30.

Find the divisors of each number and extract the common value.

Divisors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Divisors of 48: 1, 2, 3, 5, 6, 10, 15, 30

Therefore, the common factor is the common 1, 2, 3, 6.
