Reduces a fraction to its lowest terms by dividing both numerator and denominator by their Greatest Common Divisor (GCD). A fraction is fully simplified when the GCD equals 1.
The Euclidean algorithm (300 BCE) finds the GCD by repeatedly subtracting the smaller from the larger. It remains one of the oldest algorithms still in everyday use.
Stopping before fully simplified — 12/18 → 6/9 (÷2) is only half done; keep going: 2/3 (÷3) is fully simplified.
