i think prime numbers
Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.
None. 251 is a prime number.
By dividing it by a number that will make the outcome prime.
The concepts of "prime numbers" and "composite numbers" make sense for integers (whole numbers), not for arbitrary real numbers.
7 is a prime number; its only prime factor is 7.
A mirror prime.
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.
There is a difference of 95 when the prime number 2 is subtracted from the prime number 97.
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
No, for example you can't create the number 65, which is not a prime number, by adding any two prime numbers.
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.
