WebSo far we have shown that a2 is even. Then by Lemma 1, a is even. Thus k Z a = 2k. Now, we will show that b is even. From before, a2/b2 = 2 2b2 = a2 = (2k)2. Dividing by 2 gives b2 = 2k2. Therefore b2 is even and from Lemma 1, b is even. More Complex Proof (cont.) But, if a is even and b is even then they have a common factor of 2.
