Division Steps

48 = 2 * 18 + 12

18 = 1 * 12 + 6

12 = 2 * 6 + 0

Algorithm

gcd(a, b) = gcd(b, a mod b)

gcd(a, 0) = a

Bezout Identity

Find x, y such that: a*x + b*y = gcd(a,b)

48 * (-1) + 18 * (3) = 6

x

-1

y

3

Properties

  • gcd(a, b) = gcd(b, a)
  • gcd(a, 0) = a
  • gcd(a, 1) = 1
  • a and b are coprime if gcd(a,b) = 1
  • LCM(a, b) * GCD(a, b) = a * b
