Hi, In QGIS 2.16 (and also in 2.14), there's a Statistic panel (View menu --> Panels) that offers some stats on any fields (note that only numeric fields are available in QGIS 2.14).
In 2.16, there are also aggregate functions <http://qgis.org/en/site/forusers/visualchangelog216/index.html#feature-aggregate-support-for-expressions> (min, max, mean....) you can use in any expression widget, including Field calculator. So unless I misunderstood your need, yes, it's possible to retrieve the greatest value of a field.
