Discover the simplest way to find the Greatest Common Divisor (GCD), also known as the Highest Common Factor (HCF), for a set of numbers. Our online calculator makes this fundamental mathematical operation quick and effortless, helping you with complex calculations, simplifying fractions, and various number theory problems.
Formula:
The Greatest Common Divisor (GCD) of two or more integers is the largest positive integer that divides each of the integers without leaving a remainder. It's often expressed as GCD(a, b).
For example: GCD(12, 18) = 6.
For multiple numbers: GCD(a, b, c) = GCD(a, GCD(b, c)).
