Quick Reference

GCD: Largest number that divides all input numbers
LCM: Smallest number that all input numbers divide into
Property: For two numbers a, b: GCD(a,b) × LCM(a,b) = a × b
Coprime: Two numbers are coprime if GCD = 1

Numbers: 12, 18

Greatest Common Divisor (GCD)

6

Largest common factor

Least Common Multiple (LCM)

36
