# GCF Calculator

**Greatest Common Factor ****Calculator (GCF calculator)**

What is **GCF**? **GCF** stands for **greatest common factor** in mathematics, and it is the largest number that is divisible by two or more other numbers. It is also known as **HCF (highest common factor)**, **GCD (greatest common divisor),** and **GCD (greatest common denominator)**. The GCF calculator precisely calculates the highest or greatest common of two or more given numbers in no time.

## GCF Calculator

**How to find the GCF?**

There are several methods that can be used to find the **GCF **of two or more numbers such as the factorization method and the prime factorization method. However, Mycalcu's **GCF calculator** uses the factorization method to find out the **highest common factors**.

**How to use the GCF Calculator?**

- Enter the 1st number in the 1st box
- Enter the 2nd value in the 2nd box
- Click on calculate to get the result

**How to calculate Greatest Common Factors (GCF)?**

Follow the given below simple steps to quickly and accurately calculate the GCF of two numbers.

- List down all the factors of all the numbers
- Note down all the common factors
- The greatest number that is in the common factors is your answer

Let's look into an example for better clarification of the concept, let's find the **GCF** of (18, 27)

Factors of the first variable which is 18 are **1**, 2, **3**, 6, **9**, 18.

Factors of the second variable which is 27 are **1**, **3**, **9**, 27.

The common factors of 18 and 27 are 1, 3, and 9.

Therefore, the **GCF** (18,27) is 9.
