Greatest Common Factor (GCF) Calculator
What Is GCF (Greatest Common Factor)?
The Greatest Common Factor (GCF) is the largest number that divides two or more numbers exactly without leaving a remainder. It is also referred to as the Highest Common Factor (HCF).
Examples:
GCF of 8 and 20 → 4
GCF of 18 and 45 → 9
Understanding the GCF is essential for fraction simplification, solving ratio problems, and preparing for math competitions.
Why Use a Greatest common factor Calculator?
Manually calculating GCF can be error-prone when dealing with multiple numbers or large values. Using an online GCF’s calculator with steps helps:
Save time and reduce errors
Get instant results
Learn step-by-step solutions
Practice for exams efficiently
It is suitable for beginners learning factors as well as advanced students tackling complex problems.
How GCF Is Calculated?
There are several methods to find GCF:
Prime Factorization: List all prime factors and multiply the common ones.
Division Method: Repeatedly divide numbers until a remainder of zero is achieved.
Euclidean Algorithm: Efficient method for large numbers or multiple values.
A GCF calculator maths tool automates these methods and shows step-by-step solutions.
GCF’s Calculator with Steps:
Unlike basic tools, this GCF calculator with steps explains the calculation process clearly:
Example: GCF of 18 and 45
Prime factors of 18: 2 × 3 × 3
Prime factors of 45: 3 × 3 × 5
Common factors: 3 × 3 = 9
GCF = 9
Step-by-step explanations help learners understand how the answer is derived instead of memorizing results.
GCF of Two Numbers Example
Common examples include:
GCF of 8 and 20 → 4
GCF of 18 and 45 → 9
GCF of 24 and 36 → 12
The calculator works for multiple numbers as well, making it versatile for homework, exams, and practice.
GCF vs LCM
The GCF and LCM (Lowest Common Multiple) are related concepts:
GCF: Largest number dividing two or more numbers exactly
LCM: Smallest number divisible by two or more numbers
Using an LCM and GCF calculators together helps solve fraction problems, ratios, and algebraic expressions efficiently.
