To find the GCF by factoring, list out all of the factors of each number or find them with a Factors Calculator. The whole number factors are numbers that divide evenly into the number with zero remainder. Given the list of common factors for each number, the GCF is the largest number common to each list. The factors of 18 are 1, 2, 3, 6, 9, 18.

## How does the greatest common factor calculator work?

The Greatest Common Factor Calculator solution also works as a solution for finding: What is the Greatest Common Factor? The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

## How to find the GCF of two numbers using factoring?

In order to find GCF of two numbers using Factoring list out all factors of each number. Whole number factors are those that divide the number evenly leaving a remainder zero. Once you know the list of common factors GCF is the largest number common in each of the list. Find the GCF of numbers 36 and 45?

**What is the GCF of 18 and 21?**

The GCF is also known as the Highest Common Factor (HCF) Let us consider the example given below: For example – The GCF of 18, 21 is 3. Because the factors of the number 18 and 21 are: Factors of 18 = 2×9 =2×3×3. Factors of 21 = 3×7. Here, the number 3 is common in both the factors of numbers.
