Aug 1, 2025 · The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder.

When one of a and b is zero, the GCD is the absolute value of the nonzero integer: gcd (a, 0) = gcd (0, a) = |a|. This case is important as the terminating step of the Euclidean algorithm.

Tool to compute GCD. The greatest common divisor of two integers is the greatest positive integer which divides these two integers simultaneously.

Jul 23, 2025 · The GCD (Greatest Common Divisor), also known as the HCF (Highest Common Factor), is the largest positive integer that divides two or more numbers without leaving a remainder.
