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.

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.

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

No. 2 is a prime number, and any product of 2 and another prime number will be even.

Discounting the exception where the two numbers are 1 and some prime, products of two numbers will not result in a prime number. That results because that result, whatever it might be, will be divisible by 2, in addition to 1 and itself. And as it's divisible by two it's not a prime. So, no, in general a product of two numbers will not be a prime result. ANS.

No, the product of two prime numbers is unique.

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, none can.

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

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

There are only two prime numbers that are consecutive numbers, 2 and 3. Their product is 2 x 3 = 6. The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)

Here are some facts about prime numbers:1. Prime numbers have exactly two factors - 1 and the prime number itself.2. The only even number that is prime is 2.3. There are an infinite number of prime numbers.4. Every number can be uniquely represented as a prime number or a product of prime numbers.

A number that is not a prime number is called a composite number because it can be made by multiplying prime numbers together. For example, 6 is a composite number that is the product of multiplying the prime numbers 2 and 3 together.

There are not two prime numbers whose product is 64. The prime factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2, which is 2 to the 6th power. These are the only prime numbers that can be multiplied together to result in 64. There are six of them, not two. The only pair of numbers whose product is 64 that includes one prime number is 2 x 32, but only one number is prime.

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.

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

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 only prime number that is an even number is 2, and there is no prime number that can be multiplied by 2 that gives 44 as the product.

If the second number is a multiple of the prime number, than the LCM is the second number. If the second number is not a multiple of the prime number, then the two numbers are relatively prime, and the LCM is the product of the two numbers.

1 and 2, whose product is 2.

Yes, it is. Any whole number times an even number will be even. This is because whole numbers can be represented as the product of their prime factors. Every even number contains 2 as a prime factor (thereby excluding all even numbers above 2 from being prime.) Additionally, the product of any two numbers is equal to the product of their prime factors. This means that the result of multiplying an even number by a whole number will always have a prime factor of 2, making it an even number.

A composite number can be expressed as the product of two or more prime numbers. For example, 30 (composite) is 2 x 3 x 5 [2, 3 and 5 are prime] A prime number cannot be expressed as the product of other numbers. By convention the numbers zero and 1 are neither prime nor composite.

As a product of its prime factors: 2*3*13 = 78

Yes
