What is HCF (GCD)?

HCF, or Highest Common Factor, also known as GCD (Greatest Common Divisor), is the largest number that divides two or more numbers exactly without leaving a remainder.

For example:

  • Numbers: 12 and 18
  • Common factors: 1, 2, 3, 6
  • HCF/GCD: 6

HCF is commonly used in mathematics, algebra, simplifying fractions, and solving problems related to ratios and divisibility.
