Need to find the First and Last Date item had activity

I would create a formula to return the first activity date in one column and last activity date in the next column for all items in my spreadsheet. Attached is a screen shot of how the spreadsheet currently looks. The numbers in column A are unique and the dates in columns C-UJ are dates ranging from 01/02/15 - 01/31/17.
Thanks.
