No. If you multiply any numbers, those numbers are factors of whatever product you get. Therefore, this product is a composite number; it has atleast the two factors you multiplyed before. Compposite numbers are never prime.

If the two factors above were prime, you would still end up with a composite number.

For example: 3 times 5 equals 15. The factors of 15 are 1, 3, 5, and 15. 15 is composite.

7 time 51 equals 357. The factors of 357 are 1, 7, 51, and 357. 357 is composite.

How can you prove there is no largest prime number?

No. No matter how large of an example you choose, someone always can find a larger number (of any kind), because the upper range of number is infinite. If you take all the known prime numbers and multiply them together, then add 1 to the result, you will have a number that is not divisible by any of the known prime numbers. This number will either be prime or have prime factors that were not previously known. So, in this way, you can always find a new prime number or a number that is a multiple of new prime numbers. If the known prime numbers include all the prime numbers up to the largest known, the new ones must be larger.

Are odd numbers always a prime number?

No.


Are there prime numbers over 400?

Yes, in fact, there is no last prime number - the set of prime numbers is infinite. The proof was already known 2000 years ago: If you assume that there is a last prime number, multiply all prime numbers up to that "last prime number". Then add one. The result is either a prime number itself, or it is composed of factors, none of which is one of the prime numbers you multiplied (because of the added 1). Thus, the original assumption (that there is a last prime number) has to be false. Example: The first 3 prime numbers are 2, 3, 5. If you multiply them, you get 30. Add one to the result, and you get 31. This number isn't divisible by 2, by 3, nor by 5. It happens to be a prime, but this isn't always so.


What are some prime numbers that are multiply to 11?

Will the product of any prime numbers greater than one but less than twenty ever be prime?

No. If you multiply two prime numbers, any prime numbers, the result will - by definition - not be a prime number. For example, if you multiply 2 x 3, the result will obviously be divisible by 2 and by 3, and therefore, not be a prime number. By the way, one is not usually considered a prime number.


Does two prime numbers always add up to an even number?

No, they do not. If one of the prime numbers is 2, you will have an odd number.
