GCD(100, 150, 200, 250, 300) = 50

How to Use

Input the numbers for which you want to find the GCD. You can enter multiple numbers separated by commas.

GCD

The Greatest Common Divisor, commonly known as GCD, is a fundamental concept in mathematics that plays a significant role in various numerical and mathematical computations. Also known as the Greatest Common Factor (GCF) or Highest Common Divisor (HCD), it represents the largest positive integer that divides two or more numbers without leaving a remainder.

Key Properties and Applications

  • Divisibility Check: The GCD of two numbers can help determine whether they share common factors, providing insights into their mathematical relationship.
  • Simplification: The GCD is used to simplify fractions. By dividing both the numerator and denominator of a fraction by their GCD, the fraction is reduced to its simplest form.
  • Modular Arithmetic: In modular arithmetic, the GCD is used to find solutions to linear congruences and modular equations.
  • Cryptography: The GCD has applications in number theory and cryptography. It's a fundamental tool in algorithms for tasks such as generating secure prime numbers.
  • Polynomial Factorization: The GCD can be employed to factorize polynomials, simplifying complex expressions.
