What are the pairs of prime numbers where their sum and difference are also prime numbers?
2 and 5 are one such pair.
Can prime numbers other than 2 and 5 ever be 3 apart and how?
No. For two integers to have a difference of 3, one must be odd and one must be even. The only even prime number is 2. That means the only pairs of prime numbers that have a difference of 3 must be 2 and another number. The only numbers that could have a difference of 3 are -1 and 5. Since -1 is not a prime number, that is not a pair that meets this description. Since 5 is a prime number, the pair of 2 and 5 is the only possible pair of prime numbers that can have a difference of 3.
What two numbers have a difference of 2?
There are an infinite set of pairs of numbers which have a difference of two.
Two prime numbers whose difference is 2 are called?
Twin primes
How many pairs of prime numbers equal 999?
One. 997 and 2
Which pairs of prime numbers have difference of 5?
7 and 2 are the prime numbers having a difference of 5.
What are the pairs of prime numbers where their sum and difference are also prime numbers?
2 and 5 are one such pair.
How many pairs of prime numbers have a difference of 3?
Only 1 pair of prime numbers, 2 and 5, have a difference of 3. All prime numbers greater than 2 are odd so will have an even difference.
Are co-prime numbers and twin prime numbers the same?
No - co-prime numbers are pairs of numbers which share no positive integer factors apart from 1. Twin prime numbers are a pair of prime numbers with a difference of 2.
What are all the pairs of prime numbers that are consecutive numbers?
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
What are the pairs of prime factorization with a difference of 2 in 100?
The prime factorization of 100 is 2x2x5x5. There are no pairs of prime factorization with a difference of two in the number 100.
Can prime numbers other than 2 and 5 ever be 3 apart and how?
No. For two integers to have a difference of 3, one must be odd and one must be even. The only even prime number is 2. That means the only pairs of prime numbers that have a difference of 3 must be 2 and another number. The only numbers that could have a difference of 3 are -1 and 5. Since -1 is not a prime number, that is not a pair that meets this description. Since 5 is a prime number, the pair of 2 and 5 is the only possible pair of prime numbers that can have a difference of 3.
What are the 10 two digit prime numbers that are the sum of two prime numbers?
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
What two numbers have a difference of 2?
There are an infinite set of pairs of numbers which have a difference of two.
What 2 prime numbers will give a difference of one?
The prime numbers 2 and 3.
What are the factor pairs of 24 in prime numbers?
The prime factors of 24 are 2 and 3
What is the greatest prime number that is the sum of 2 prime numbers and is the difference of 2 prime numbers?
5
