      S

      @thoughtfulmongoose Let a=2x and b=2y, then the question is asking for the GCD of 2x and 4y. Obviously 2 is a common divisor, but we don't know if x has any more 2s in it. If x has one more factor of 2 and y has none then the greatest common divisor is 4. So the answer should be NEI(not enough info)

      @zestfulalbatross-0 I did the same way except that I thought of the clusters as immovable bundles. I think clusters is a better way of illustrating the problems.
