What does "not the least of which" mean? [duplicate]

I think "not the least of which" means "one of the biggest" or "one of the important".
Is it right?


Solution 1:

The phrase can be used to mean "one of the biggest" or "one of the most important." However, this meaning isn't necessarily the meaning implied by the speaker. Taken literally, it means that the object in question or the person to whom one is referring is not the member or object considered to be the least important (or the smallest) in the referenced group.
