2 and 3
The only two consecutive numbers that are both prime are 2 and 3. Since there are no other even prime numbers (other than 2), there are no more pairs of consecutive prime numbers. Therefore, the term "twin primes" usually refers to pairs of prime numbers that are 2 numbers apart. Examples are (3, 5), (5, 7), (11, 13), (101, 103), and many others more. It is not currently know whether there are infinitely many twin primes.
2 and 3 are the only consecutive primes.
No.
2 and 3 are the only consecutive numbers that are prime.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
The longest string of consecutive numbers that are primes is two digits long, consisting of 2 and 3 only. There are no other consecutive numbers that are primes because no even numbers greater than 2 are primes.
There are an infinite number of prime numbers which are consecutive odd integers. Choose any natural number n. Take all primes up to any number n, take their product, and add 1 and subtract 1 from it. These 2 numbers are consecutive odd integers. eg 2*3*5*7 = 210 209 and 211 are primes which are consecutive odd integers.
Any number greater than one can be co-prime. I guess the answer is 49.
Consecutive numbers will always total an odd number. Consecutive odd numbers or consecutive primes would be 5 and 7.
There is just one group: 2 and 3. No other primes are consecutive.
No. Twin primes are two consecutive odd numbers that are prime, such as 17 and 19.
yes, 1 and 2
