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.
10
Since 146 is a factor of 584, it is automatically the GCF.
As written, the GCF is 1. I've seen this question often with 52, 143 and 156 where the GCF is 13.
