What else can I help you with?
13 and 15 are twin prime?
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.
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.
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.
List all prime numbers?
Euclid proved there are infinite. He said that if there were a finite number of primes, if you multiply all the primes together and then add 1, the result will be a prime. Thus, there are infinite primes.
Is there a pattern in the prime and composite numbers between 1 to 100?
There are some patterns, but none that can help you determine, in all cases, whether the number is a prime or not.For example: * All primes except 2 are odd numbers. However, not all odd numbers are primes. * All primes greater than 3 are of the form 6n - 1, or 6n + 1. However, not all numbers of this form are primes.

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.
How many primes are there in 1 to 1000?

What is the proof about multiplying twin primes and adding 1?
The question depends on what it is that you want to prove!
