Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.

The largest division of time on the geologic time scale is an eon. Eons are subdivided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic, began around 541 million years ago and is divided into the Paleozoic, Mesozoic, and Cenozoic eras.

After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
