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

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.
3 and 5 are prime numbers but if you mean 13 14 15 18 then it is 13

Sometimes. 13 is a prime number. 13/26 can be simplified to 1/2. But 13/15 cannot be further simplified.
Actually, 13 and 15 are not twin primes because twin primes are pairs of prime numbers that have a difference of 2 between them. In this case, 13 is a prime number, but 15 is not a prime number because it can be divided by 3 and 5 in addition to 1 and itself. Therefore, 13 and 15 do not meet the criteria to be considered twin primes.
