About Greatest Common Factor

The Greatest Common Factor (GCF), also known as the Greatest Common Divisor (GCD) or Highest Common Factor (HCF), is the largest positive integer that divides each of the given numbers without a remainder.

Applications of GCF
  • Simplifying fractions to their lowest terms
  • Finding the Least Common Multiple (LCM)
  • Solving linear Diophantine equations
  • Cryptography and modular arithmetic
  • Polynomial factorisation
Example

To find the GCF of 24 and 36:

  1. Prime factorisation of 24: 2³ × 3
  2. Prime factorisation of 36: 2² × 3²
  3. Common prime factors: 2² × 3
  4. GCF(24, 36) = 2² × 3 = 12
