13 and 15 are twin prime?
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).
Two consecutive prime numbers which differ by 2 are said to be twin primes while two numbers whose hCF is 1 are called co-primes how many pairs of co-primes are between 1 and 50?
Any number greater than one can be co-prime. I guess the answer is 49.
What is the Number of prime numbers between 1 and 10 inclusive?
The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7
Are all numbers between twin primes divisible by six?
Yes, all primes over three are either of the form 6n - 1 or 6n + 1. So the only way for them to be prime pairs is for one to be of the same n, one -1 and the other +1; so the number between them is always of the form 6n, and thus always divisible by six.

What are the twin primes from 1-50?
Twin primes are pairs of prime numbers that have a difference of two. The twin primes between 1 and 50 are: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), and (41, 43). These pairs are the only twin primes found within that range.

All co primes twin primes. True or false?
False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.
