Date Range formula for last date


I hope someone can help.   

I am trying to create a formula in Smartsheet that can pull the last date (i.e. the latest date) from a range of cells.  E.G.: I have x number of dates in a range of cells in column E and I want to create a formula to look at the range and show the last date in that range.  I must admit I am not a formula guru by any stretch of the imagination.

Any help would be greatly appreciated.
