G, P, and Q are integers, P = K + 6; G is the greatest common factor of P and Q. G =?

(1) Q = 2531.

(2) Q = K + 7.

From 1,
no information about P...not sufficient

From 2
P and Q are consecutive integers and consecutive integers are all always co-prime..hence G=1...sufficient

Ans option B

GCD of (a,0)=|a| for a not equal to zero since any number is a divisor of 0, and the greatest divisor of a is |a|.
So, HCF of (0,1)=1

Then B is the best answer!

as LR rightly pointed out, consecutive integers are co-prime...HCF is 1
