What is HCF (Highest Common Factor)?
The HCF (Highest Common Factor) is the largest number that divides two or more numbers exactly without leaving any remainder. It is also known as the GCF (Greatest Common Factor).
For example:
- The HCF of 12 and 18 is 6
- The HCF of 24, 36, and 48 is 12
Using this HCF calculator online, you can easily find the highest common factor of numbers.

How to Find HCF of Numbers?
To find HCF, identify the largest number that divides all given numbers exactly. You can use methods like prime factorization, division method, or simply use this HCF calculator online for instant results.
HCF Formula
HCF × LCM = Product of two numbers
This formula is useful for solving problems quickly and understanding the relationship between HCF and LCM.
Step-by-Step HCF Example
Find HCF of 18 and 24:
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Common factors: 1, 2, 3, 6
HCF = 6
Methods to Calculate HCF
There are different methods to calculate HCF manually:
Method 1:
Prime Factorization Method
Break each number into its prime factors and multiply the common factors.
Example:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
HCF = 2 × 3 = 6
Method 2:
Division Method (Euclidean Algorithm)
Divide the larger number by the smaller number repeatedly until the remainder becomes zero.
Method 3:
Listing Factors Method
List all factors of each number and choose the highest common factor.
