This shows how to relate the problem of measuring water with two different pitchers and divisors.
Common Divisors - 1. Let d; a; b; r, and q be integers.
a) Suppose that d|a and d|b. Show that d|(ra + qb).
b) Suppose a = qb + r. Show that the set of common divisors of a and b
is the set of common divisors of b a ...
Greatest Common Divisors ( GCD ) - 1. Let a, b be positive integers, and write a = qb + r, where q, r are Elements of Z and
0 (= or)< r < b. Suppose that d = gcd(a, b).
a) If r = 0 show that d = b.
b) If r > 0 show that d = gcd(b, ...
