Yes because they all have only 2 factors which are themselves and one
Well, there is a clear definition, and at least in theory you can always determine whether a number is a primer number or not, so I would say, yes.
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
All of the numbers from 1 to 100 are the factors in the set of numbers from 2 to 100.
Proper factors of a number do not include 1 or the number itself. For example, all of the factors of 6 are 1, 2, 3, and 6, but the proper factors of 6 are 2 and 3.
Yes it is.
Yes because they all have only 2 factors which are themselves and one
Prime numbers have only 2 factors and their set is not well defined because they do not follow an orderly mathematical pattern.
its not well defined because not all the students/people like the teachers,so it is not well defined
Elements that have to be defined by personal judgement. Such as the set ofgreat songs is not well-defined. But the set of the English alphabet is well-defined.

A well defined set is one that you know exactly what is meant when you read it. For example, the set of all people 6' 1" tall is well defined. Whenever you meet someone, if they're 6'1" tall, they're in the set. Otherwise, they're not. You know exactly what I mean. So that set is well defined. The set of all cute shoes is not well defined. Jane just adores buckles, so any shoe with a buckle is cute to her. But Martha likes plain shoes. Buckles are big, ugly things that detract from the shoe. So a shoe with a buckle is not cute to Martha. So the set of all cute shoes is not well defined, because you can't just look at it and determine if it belongs in the set. So the set of all buckled shoes would be well defined, but the set of all cute shoes is not.

well defined
If there exists even one single item for which you cannot say whether it is in the set or not, the set is not well defined.
