HCF Calculator

hat is HCF?

HCF stands for Highest Common Factor, which is the greatest number that divides two or more numbers exactly. For example:

  • The HCF of 18 and 24 is 6, since 6 is the largest number that divides both 18 and 24 without leaving any remainder.
  • The HCF of 45 and 60 is 15.

HCF is commonly used in:

  • Simplifying fractions
  • Solving ratio problems
  • Dividing resources equally
  • Reducing mathematical equations to simpler forms

Example of HCF Calculation

Let’s walk through an example using the calculator:

Example 1:

  • Input: First Number = 56, Second Number = 98
  • Calculation:
    • Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
    • Factors of 98: 1, 2, 7, 14, 49, 98
    • Common factors: 1, 2, 7, 14
    • Highest common factor = 14
  • Output: HCF = 14

Example 2:

  • Input: First Number = 48, Second Number = 180
  • Common divisors = 1, 2, 3, 6, 12
  • Highest = 12
  • Output: HCF = 12
