What the tool does, how to run it, and what to expect from the result.
The greatest common factor is the largest number that divides every input. Take the primes the numbers share at their lowest power: 48 = 2⁴ × 3 and 180 = 2² × 3² × 5 share 2² × 3 = 12. The calculator uses Euclid’s algorithm, so large numbers are instant.
