The numbers are 13 and 41. And you do not need to know that they are prime in order to find the answer. The sum (54) and difference (28) provide all the necessary information.
All numbers are divisible by 1. So, apart from the number 1, all numbers are divisible by another number. These numbers are therefore prime or composite.
no all even numbers apart from 2 are not prime numbers :)
A mirror prime.
None. If it is a multiple of another number, in this case 4, it is not a prime number.
no. 3 and 11 are prime numbers. 12 is not a prime number as it can be divided by other things apart from itself and one. these other numbers are 3, 4, 6 and 2.

1597 is a prime number. You cannot multiply prime numbers to create another prime number.
No. Numbers and luck have nothing to do with one another apart from superstitious belief.
Any even number is always divisible by 2 and thus (apart from 2 itself) all even numbers can not be prime numbers.
A number is relatively prime to another number or set of numbers when their GCF is 1.
A mirror prime.
None. If it is a multiple of another number, in this case 4, it is not a prime number.
Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.
no. 3 and 11 are prime numbers. 12 is not a prime number as it can be divided by other things apart from itself and one. these other numbers are 3, 4, 6 and 2.
The first two prime numbers add up to another prime number.
You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)
