Do you mean what is a number that has exactly two factors? If so the answer is a Prime number. Eg. 2,3,5,7,11..... They are only divisible by 1 and themselves

If a number has equal factors, it is a perfect square and the equal factors would be square roots.
24 has eight factors, which means it has six proper factors.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
It depends on whether 1 is considered a factor. If yes, then the answer to the question is no, since 1 and the number itself are the two factors implying that it is a prime. If 1 is not considered as a factor, then the square of any prime meets the requirements. If p is a prime, then p and p2 are the only two factors of p2.

A prime number has exactly two factors.
If a number has equal factors, it is a perfect square and the equal factors would be square roots.
By definition, all prime numbers have exactly two factors. There is not a prime number that has only one factor.
The number 1 or a factor.

Prime numbers have exactly two factors.
The smallest number that has exactly eight factors is 24. The factors of 1,2,3,4,6,8,12, and 24
1 is the only number that has exactly one factor. A prime number has exactly two factors, 1 and the number itself. A composite number has more than two factors.
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
24 has eight factors, which means it has six proper factors.
There are exactly two whole number factors of any prime number. The first factor is '1'. The other factor is the prime number itself.
