GCF Calculator

Last Updated : 2 Mar, 2026

The GCF, GCD, or HCF Calculator is a tool that can input numbers separated by commas, and the calculator will provide their GCD.

Steps to Use the GCD/HCF Calculator

To use the provided GCD Calculator, you can use the following steps:

Step 1: Input the numbers for which you want to find the greatest common divisor (GCD). Separate the numbers by commas or spaces.

Step 2: Click the 'Calculate' button.

Step 3: The calculator will provide you with the result, which is the GCD/HCF of the entered numbers.

Step 4: If you have more sets of numbers to calculate GCD/HCF for, you can clear the current input or enter new numbers and repeat the process.

GCD (Greatest Common Divisor) :

  • Greatest Common Divisor (GCD), also called HCF or GCF, is the largest positive integer that divides two or more numbers exactly.
  • It is the greatest number that can divide the given numbers without leaving any remainder.

For example, consider the numbers 12 and 18. The divisors of 12 are 1, 2, 3, 4, 6, and 12, while the divisors of 18 are 1, 2, 3, 6, 9, and 18. The largest number that both 12 and 18 can be divided by without leaving a remainder is 6. Therefore, the GCD of 12 and 18 is 6.

Is HCF same as GCD

Yes, HCF (Highest Common Factor) is the same as GCD (Greatest Common Divisor).

As both HCF or GCD represents the largest positive integer that can divide two or more numbers without leaving a remainder. So, HCF and GCD essentially convey the same idea and are used in different regions or educational systems interchangeably.
