For example, 6 and 35 factor as 6 = 2 × 3 and 35 = 5 × 7, so they are not prime, but their prime factors are different, so 6 and 35 are coprime, with no common factors other than 1. A 24×60 rectangle is covered with ten 12×12 square tiles, where 12 is the GCD of 24 and 60.
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
Product = 2 × 2 × 2 × 2 × 3 × 2 × 2 × 3 × 3 × 5 = 8640. This also works for the greatest common divisor (gcd), except that instead of multiplying all of the numbers in the Venn diagram, one multiplies only the prime factors that are in the intersection. Thus the gcd of 48 and 180 is 2 × 2 × 3 = 12.
Extended GCD algorithm Input: a, b, univariate polynomials Output: g, the GCD of a and b u, v, as in above statement a 1, b 1, such that a = g a 1 b = g b 1 Begin (r 0, r 1) := (a, b) (s 0, s 1) := (1, 0) (t 0, t 1) := (0, 1) for (i := 1; r i ≠ 0; i := i+1) do q := quo(r i−1, r i) r i+1 := r i−1 − qr i s i+1 := s i−1 − qs i t i+1 ...
For example, if the polynomial used to define the finite field GF(2 8) is p = x 8 + x 4 + x 3 + x + 1, and a = x 6 + x 4 + x + 1 is the element whose inverse is desired, then performing the algorithm results in the computation described in the following table.
