## Quick Answer

Find the greatest common factor (GCF) of two or more numbers. Enter your integers to see the largest common divisor and prime factorization steps.

## Definition

A GCF calculator (Greatest Common Factor) is an arithmetic tool that finds the largest positive integer that divides two or more integers without leaving a remainder. The calculator processes the input numbers and evaluates their factors using methods such as prime factorization, lists of factors, or the Euclidean algorithm. It displays the greatest common factor along with the detailed calculations for each method. Students and math teachers use this tool to simplify fractions, factor algebraic expressions, and solve word problems.

## How to Use

1. **Enter your numbers** — Type two or more integers separated by commas in the input area.
2. **Choose GCF method** — Select the calculation method, such as listing factors or prime factorization.
3. **Read the result** — View the greatest common factor, list of common divisors, and step-by-step factorization.
