Why can there never be a pair of consecutive prime numbers that are both prime?
If you mean consecutive numbers that are prime? than the answer is 2,3 are consecutive numbers which are prime. except for this pair it is impossible for consecutive numbers to be prime because every second number is multiple of 2
Who do you know that there are no other consecutive numbers besides 2 and 3?
Both prime number
How do you know twin prime number?
You take two consecutive odd numbers and check both of them to see whether they are prime or not.
How are 2 and 3 consecutive prime numbers?
2 and 3 are consecutive numbers and they are both prime.
What are prime factors of 62?
the prime factors are 2 and 31. Both of these numbers can not be divide by any other whole number to get another whole number therefore they are called prime.
What is a consecutive prime numbers?
Consecutive prime numbers are 2 integers that differ by 1 and are both prime. Since 2 is the only even prime, 2 and 3 are the only consecutive primes.
What whole number less than 20 is both an even and prime number?
2
What you mean by co-prime number?
Two number are co-prime if there is no whole number other than 1 that divides them both exactly
Why aren't there any other pairs of consecutive prime numbers?
Ah hah! You didn't say so, but you must be talking about 2 and 3 ... the only two consecutive numbers that are both prime numbers. There can't be any others. Because if you have any other two consecutive numbers, one of them has to be an even number ... divisible by 2. Since that number is divisible by 2, it's not a prime number.
What are consectutive whole numbers?
"Consecutive" means that both of them are almost the same number,except that one of them is 1 more than the other one.If you're counting, then when you get to one of the consecutive whole numbers,the other one will be the very next one you say.
Why isn't 8 nor 9 a prime number?
If it is divisible by a whole number that isn't 1 and gets another whole number, it is not prime. 8 is divisible by both 2 and 4. 9 is divisible by 3.
Why are 2 and 3 consecutive prime numbers?
A prime number is a number only divisible by 1 and itself, since nothing else goes into 2 but 1 and 2 and nothing goes into 3 but 1 and 3 they are both prime and since 3 goes after 2 they are consecutiveAnd they are the ONLY consecutive prime numbers because if you have one prime number (i.e. 29), then there always is an even number right after the prime number (i.e. 30 comes right after 29), and consecutive means "right next to," right? And we all know that even numbers can always be divided in half, so 2 and 3 are the only consecutive prime numbers.1 is not a prime so that (1,2) is not a pair of consecutive integers that are prime. So, if there is another opair of consecutive numbers that are prime, they must be larger than (2,3) - ie the smaller of the pair must be greater than 2.Now any pair of consecutive numbers must have one odd and one even number. Therefore, the candidate pair must contain an even number which is greater than 2. But all even numbers greater than 2 are divisible by 2 and so are composite (non-prime). So every such candidate pair contains an odd number which may or may not be prime, and an even number which is definitely not a prime.
