I have no idea how to do this...

Suppose that on Wednesday a ipod company earns $17197 from selling ipods @ an even dollar price which is greater than $1 and on Thursday the ipod store earns $17371 from selling ipods @ that same even dollar price as on Wednesday. Determine the number of ipods the company sold each day and @ what even dollar price (greater than $1)?

So I'm confused by this "even dollar" thing.

I thought of just finding the GCD(17197, 17371) which is 29, then dividing each of those numbers by it...

So 17197/29 = 593 and 17371/29 = 599

Not sure what this says or what to do now. Thanks for the help.
