Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
only one has and that is the number 3
Believe it or not, the number of prime numbers beginning with 8 is infinite.
there are 13 primes not 5.
There are an infinite number of twin primes. This is true, but as yet there has not been published a valid proof of it. Perhaps soon someone will publish a valid proof.
Five of them.

Suppose a composite number x can be expressed as a product of primes p, q, r ... in exponential form as x = pa*qb*rc ... has (a+1)*(b+1)*(c+1) ... factors. So, the bigger a, b, c etc are, the greater the number of factors.

the answer could have something to the ratio of prime numbers between 0 and 9 to the the number of prime primes between 9 and 625 and the number of primes between the square 25x25. Hint: the are 9 primes between 0 and 25. There are 114 primes between 25 and 625. There is a square number somewhere near 1000. 961 which is the Mercienne prime number 31 squared. without giving the answer away, by dividing 625 by 9 we get the ratio 12.6666667 or 12 and 2 3rds. this is one of many ratio to help find how many prime numbers within a given range. once the precise ascending pattern of prime numbers is discovered then any prime number to infinity can be calculated and identified disclosure: this information is designed to provide food for thought on the matter of the question above and is not a precise answer.
Two distinct prime factors, four altogether.
One; the only even prime number is two.
Believe it or not, the number of prime numbers beginning with 8 is infinite.
The only even prime number is... 2 !
