Frequently Asked Questions
What is HCF?
HCF (Highest Common Factor) or GCD (Greatest Common Divisor) is the largest number that divides all given numbers without a remainder. Example: HCF of 12 and 18 is 6.
How is HCF calculated?
Our tool uses the Euclidean algorithm: repeatedly divide the larger number by the smaller until the remainder is zero. The last non-zero remainder is the HCF.
Can I find HCF of more than two numbers?
Yes – enter as many numbers as you need, separated by commas, and the tool calculates the HCF of all of them.
What is HCF used for?
HCF is used to simplify fractions, divide quantities into equal groups, and solve problems in number theory and algebra.
Is this tool free?
