The GCF of 137 and 230 is 1. 137 is prime, and so its only factors are 1 and 137. Since 137 is not a factor of 230, the GCF of 137 and 230 is 1.

As written, the GCF is 1. I've seen this question often with 52, 143 and 156 where the GCF is 13.
Since 146 is a factor of 584, it is automatically the GCF.
