There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.

Find all pairs of consecutive prime numbers?

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.

How many pairs of prime numbers have a sum of 50 and 60?

47 + 3 = 50, 43 + 7 = 50, 37 + 13 = 50, and 31 + 19 = 50. 4 pairs of prime numbers have a sum of 50. 53 + 7 = 60, 47 + 13 = 60, 43 + 17 = 60, 41 + 19 = 60, 37 + 23 = 60, and 31 + 29 = 60. 6 pairs of prime numbers have a sum of 60.


Are there any 2 numbers that don't have a common factor?

Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.

Are there infinitely many natural numbers that are not prime?

This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.


What pair of prime numbers that differ by 2?

They are called twin primes and there are thought to be infinitely many such pairs.
