None. 251 is a prime number.

Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.

The three prime numbers that make 455 when multiplied are 5 x 7 x 13.

Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.

Look at the first 2 of these prime numbers. They cannot be even for then they would be divisible by 2, so not prime. Add them together. Two odd numbers added together make an even. Subtract this even number from 50 (also even) so the third number must be even. There is no way of adding 3 prime numbers together to make an even number.

A mirror prime.

The three prime numbers which multiply to make 231 are 3 x 7 x 11.

i think prime numbers

No, for example you can't create the number 65, which is not a prime number, by adding any two prime numbers.

All numbers have factors. These are numbers that multiply together to make the original number. Some of those factors are prime numbers. A number is prime if it only has two factors: one and the number itself.

23 is a prime number. Prime numbers are numbers that when multiplying only 1 and itself make it. Nothing but 1 and 23 equals 23 so 23 is a prime number.

The concepts of "prime numbers" and "composite numbers" make sense for integers (whole numbers), not for arbitrary real numbers.

Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.

There is a difference of 95 when the prime number 2 is subtracted from the prime number 97.

the two prime numbers will be factors of that number, which would make that number a composite number

I might be reading this incorrectly, but it seems to me that I can take two prime numbers, 3 and 3, and make the square number nine out of them. This is also true of all the other prime numbers.

225 cannot be factorised into the product of only 3 prime numbers.

7 is a prime number; its only prime factor is 7.

Yes, it can. Examples are 2 and 5 to make 10 and 2 and 7 to make 14. If your question was if they could make an even prime number, the answer is no. Two is the only even prime number.

By dividing it by a number that will make the outcome prime.

When you add two or more prime numbers you will only end up with a whole number and not a decimal number.

21

Prime Factorization is finding which prime numbers multiply together to make the original number.

5 and 8

Make sure that one of them is 2.
