These two metrics are the building blocks of number theory. GCD is the largest positive integer that divides each of the integers, while LCM is the smallest positive integer that is divisible by both.

Applications:

  • Simplifying Fractions: Divide both numerator and denominator by their GCD.
  • Scheduling: Use LCM to find when two independent periodic events will coincide.
  • Data Alignment: Essential for byte-alignment calculations in systems programming.
