16=2*2*2*2 There is only one distinct prime factor, that is 2.
Each prime number has only two factors which are itself and one.
Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.
The definition of a prime number is a number which has only two factors: 1 and itself. All prime numbers have only two factors: one and themselves. So, asking "What is a prime number that has only 2 factors one and itself" is like asking "What is a type of cocker spaniel that is a dog?"

If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.
i believe, there can only be one.
There are infinitely many prime numbers. There is only one even prime number, which is 2, because all other even numbers are divisible by 2 and thus are not prime. So, there are infinitely many odd prime numbers and only one even prime number.
