Question : Finding the oldest date from a set of max dates

I have a lot of history that I need to group by product.  I take the most recent update date for each product, then I need to get the Oldest of those most recent dates.

So I start by grouping by product ID to get the most recent update date.

 select product_id, max(updateDate)
  from productChanges
 where company_id = 123
 group by product_id

Now I need to get the Oldest from that set of data so that I have one date for company 123

I have tried this but it's giving an error...

select min(theDate)
from (
 select max(updateDate) as theDate
  from productChanges
 where company_id = 123
 group by product_id
)


What's the correct syntax to get the oldest date from a set of max() dates?

Thanks!!!
