34 is the product of the prime numbers 2 and 17.

No, the product of two prime numbers is unique.

The product of two numbers could be either a composite number or a prime number. If one of those numbers is 1 and the other is a prime number, the result is that prime number. If neither number is 1, the product of the two numbers will be a composite number. If one of those numbers is 1 and the other is not a prime number, the product will not be a prime number. So, in most cases, it will be a composite number.

If you multiply 2 prime numbers. the result will never be prime. A prime number is one that has no factors except itself and one. The number specified in the question has as factors the 2 prime numbers cited.

The prime factors of 16 are 2, 2, 2, and 2. Their product is 2 x 2 x 2 x 2 = 16. The product of the prime factors of a number is that number. Prime factorization is the unique set of prime numbers that are multiplied together to produce the given number.

There is no correct answer to this question, because it is nonsensical.The question asks for a largest prime number. By definition, a prime number is NOT the product of 2 (or more) prime numbers. So it is nonsensical to ask for any prime number that is the product of 2 prime numbers.

Yes, 64 can be a product of prime numbers. All integers are either prime numbers or a product of prime numbers (called the prime factorization of a number). The prime factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2.

No, none can.

The first prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19. The first prime number is 2 and the fifth prime number is 11. The product of these two numbers is 2 x 11 = 22.

No, the product of two prime numbers is unique.

The answer to this convoluted question is as follows: The product of prime numbers, for the composite number 64, is 2*2*2*2*2*2 or 26

How about: 2*3*5 = 30 which is the product of the 1st three prime numbers

No not always because composite numbers can be the product of 2 or more prime factors

The product of two numbers could be either a composite number or a prime number. If one of those numbers is 1 and the other is a prime number, the result is that prime number. If neither number is 1, the product of the two numbers will be a composite number. If one of those numbers is 1 and the other is not a prime number, the product will not be a prime number. So, in most cases, it will be a composite number.

In prime numbers 19+5 = 24 or as a product of its prime factors 2*2*2*3 = 24
