What is the Greatest Common Factor?
The Greatest Common Factor (GCF) – also called Greatest Common Divisor (GCD) or Highest Common Factor (HCF) – is the largest positive integer that divides each number in a given set without leaving any remainder.
Common uses: Simplifying fractions, distributing items into equal groups, and finding the Least Common Multiple using the formula LCM(a, b) = a × b ÷ GCF(a, b).
