GCF Calculator

The GCF Calculator at OkayCalculator is your go-to resource for finding the Greatest Common Factor (also called the Highest Common Factor or HCF) of any set of whole numbers in seconds. Whether you’re a student simplifying fractions, a teacher preparing lessons, or just need quick number solutions, this tool delivers accurate results with zero hassle.

What is the GCF?

The Greatest Common Factor is the largest number that divides two or more integers exactly, with no remainder. For example, the GCF of 18 and 24 is 6, because 6 is the biggest number that both 18 and 24 can be divided by evenly.

Why Find the GCF?

  • Simplifying Fractions: Reduce fractions to their simplest form by dividing numerator and denominator by their GCF.
  • Solving Math Problems: Essential for problems involving ratios, proportions, and LCM calculations.
  • Factoring Polynomials: Find common factors in algebra for easier simplification.
  • Everyday Tasks: Useful for distributing items evenly, sharing workloads, or planning events efficiently.

How to Use the GCF Calculator

  1. Enter Numbers: Type in two or more whole numbers separated by commas or spaces.
  2. Click “Calculate”: Instantly see the GCF, along with a step-by-step explanation for clarity.
  3. Review the Results: Use the answer to simplify fractions, solve equations, or further your math work with confidence.

Example Calculation

Example: Find the GCF of 32, 48, and 80.
– Enter: 32, 48, 80
– Click Calculate
– The result displays: GCF = 16
– This means 16 is the largest whole number that divides all three numbers evenly.
