Which property correctly defines the relation between GCD(ka,kb)\text{GCD}(ka, kb)GCD(ka,kb) and kkk?
GCD(ka,kb)=k⋅GCD(a,b)\text{GCD}(ka, kb) = k \cdot \text{GCD}(a, b)GCD(ka,kb)=k⋅GCD(a,b)
GCD(ka,kb)=GCD(a,b)\text{GCD}(ka, kb) = \text{GCD}(a, b)GCD(ka,kb)=GCD(a,b)
GCD(ka,kb)=k2⋅GCD(a,b)\text{GCD}(ka, kb) = k^2 \cdot \text{GCD}(a, b)GCD(ka,kb)=k2⋅GCD(a,b)
GCD(ka,kb)=k+GCD(a,b)\text{GCD}(ka, kb) = k + \text{GCD}(a, b)GCD(ka,kb)=k+GCD(a,b)
