A Prime number can only be divided by itself and 1.
4 can be divided by 2
26 can be divided by 2
15 can be divided by 3
13 is prime.
3 x 5 = 15, so 15 is not a prime number.

No, 13 is a prime number and 15 is a composite number. A composite number is a positive integer that has more than two positive divisors.
11 and 13 are prime numbers but 15 is a composite number because it has more than two factors

7 or 13
Sometimes. 13 is a prime number. 13/26 can be simplified to 1/2. But 13/15 cannot be further simplified.
13 and 15 are not twin primes because of the two, only 13 is prime (a number that is only divisible by itself and 1). 15 is not prime because it is divisible by more than itself and 1. 15 is also divisible by 3 and 5 (3 x 5 = 15).
