Key property (gcd and linear combos): If a number divides both and , then also divides any integer linear combination of them. In particular: (x+y)+(x-y)=2x,\qquad (x+y)-(x-y)=2y. 2. Use : If an odd number divides both and , then must divide and (since is odd and can’t “hide” inside the factor 2). That would force to divide both and , contradicting . Conclusion: No odd prime can divide both and . The only possible common factor is a power of . 3. Check parity cases: If one of is even and the other is odd, then are both odd. With no odd common factor (from step 2), the only possible common factor is 1. . If both are odd (still coprime), then are both even. So the gcd is at least . From step 2, no odd factor can be common, and because at least one of or is odd, you can’t get a factor in both simultaneously (see below). Therefore, the HCF is or . Correct option: (a) 1 or 2.
