How old was Vito Corleone when he died?

Excuse me, but I was wondering if you could clarify something for me. In the context of the well-known character Vito Corleone, I'm curious to know - at what age did he pass away? It's a detail that's often overlooked, but I'm fascinated by the life span and legacy of such a complex and influential figure. Could you please provide me with the information, if you happen to know it? Thank you in advance for your assistance.
