A HCF calculator is an online web based tool to find the Highest Common Factor (HCF) of two or more numbers.

To calculate the Highest Common Factor (HCF) of two or more numbers, the following methods are used:

• Prime Factorization Method:

1. Find the prime factors of each number.
2. The HCF is the product of the common prime factors with the lowest powers.

• Euclidean Algorithm Method:

1. Divide the larger number by the smaller number and take the remainder.
2. Replace the larger number with the smaller number and the smaller number with the remainder.
3. Repeat this until the remainder is 0. The divisor at that point will be the HCF.

Here’s are the reasons to use an HCF calculator:

• Time-saving: It instantly calculates the HCF without the need to list factors manually.
• Accuracy: The calculator provides the correct result, eliminating human error.
• Convenient: It simplifies complex calculations, making it accessible for students, professionals, and anyone needing quick answers.

Example: To find the HCF of 12 and 18, the HCF calculator instantly provides 6, the largest number that divides both 12 and 18 evenly.
