## Quick Answer

Find all factors, factor pairs, prime factorization, and the greatest common factor (GCF) of any integer. Enter a number to analyze its divisors.

## Definition

A factor calculator is an arithmetic utility designed to find all whole-number divisors of a given integer. It lists all positive and negative factor pairs, computes the prime factorization (the representation of the number as a product of prime numbers), and identifies the greatest common factor (GCF) when two numbers are provided. Students, programmers, and educators use this tool to simplify fractions, solve algebraic factoring problems, and analyze number divisibility in algebra and pre-algebra.

## How to Use

1. **Enter a number** — Type the whole number you want to factor into the input field.
2. **Select calculation mode** — Choose whether to find the factors of a single number or compare two numbers for the GCF.
3. **Read the factors** — View the list of all divisors, factor pairs, and the prime factorization tree.
