There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
A number has exactly three factors if and only if it is the square of a prime number.
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
3 is a prime number because it has exactly two factors which are whole numbers: itself and one. This is the definition of a prime.
A prime number, like 2, 3 or 5.
There are an infinite number of prime factorizations with exactly three factors. Without something more specific, we won't be able to narrow it down.

3 is a prime number because it has exactly two distinct factors. The only factors of a prime number are 1 and itself. The only factors of 3 are 1 and 3, so it is a prime number.
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
The square of any prime number has exactly 3 factors. They are: 1). 1 2). the number itself 3). the prime number which is its square-root

A prime number is a number with exactly two distinct factors: itself and oneThe only factors of 3 are 1 and 3 so it is a prime number.The factors of 6 are 1,2,3 and 6 which has more than two factors so it is not a prime number.
A prime number, like 2, 3 or 5.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
