What else can I help you with?
What are all the prime number pairs that differ by 5?
2 and 7 is the only such pair.
What numbers are prime but also even?
There are no other prime numbers that are even but 2.
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.
What are even numbers that are also prime numbers?
The only even prime number is 2.
What are mirror prime numbers?
They are prime numbers when you reverse the first one, the second one is prime also.
What are Write three pairs of prime numbers such that sum of each pair is also a prime number?
2+3,11+3,3+17
What are two prime numbers less than 20 who's sum is also a prime number?
(2,3) and (2,5) are the two pairs such that the sum of their elements is a prime number.
What are all the prime number pairs that differ by 5?
2 and 7 is the only such pair.
How do you change whole numbers to prime numbers?
You don't. All prime numbers are also whole numbers.
What numbers are prime but also even?
There are no other prime numbers that are even but 2.
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 are even numbers that are also prime numbers?
The only even prime number is 2.
What are mirror prime numbers?
They are prime numbers when you reverse the first one, the second one is prime also.
Are most prime numbers also odd numbers?
All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.
Why is the product of two prime numbers also prime?
It's not.
What is it called when the product of a pair of numbers is the LCM also?
The numbers are relatively prime, or co-prime.
