I have a date field on child object . receiveddate__c. I have a field on parent object mostrecentproductreceived__c. Is it possible to use workflow or process builder to update the mostrecentproductreceived__c field on parent based on the receiveddate__c. 

If there are two  child records , Record1 with  receiveddate__c = 11 May 2020 and Record2 with receiveddate__c = 1 May 2020. Then the mostrecentproductreceived__c should have the product from first record. 

if a new child record Record3 is added with receiveddate__c = 13 May 2020 then mostrecentproductreceived__c should be the product from this record. 

If Record1 is updated receiveddate__c = 14 May 2020 then mostrecentproductreceived__c should be the product from this record. 

How can I do this?
