What two prime numbers have a difference of one?
3 and 2 are the only prime numbers with a difference of 1.
When is the only time 1 is the difference of two prime numbers and they are 2 and 3?
As the number 2 is the only even prime number then a difference of 1 occurs only between 2 and 3. All other prime numbers are odd and therefore the minimum difference between successive prime numbers is 2.
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.
What is the difference to composite and prime numbers?
prime numbers are numbers that can only be divided by one and itself. Composite numbers can be divided by more than one and itself.
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 prime factors of 8 with a difference of 2?
The only prime factor of 8 is 2. You need at least two numbers to have a difference.
What is differences between prime number and compost number?
The difference between prime and composite numbers is simple. Prime numbers have only two factors, 1 and itself. Composite numbers are divisible by more than two numbers
The only prime number that is a sum and a difference of two prime numbers?
5; (3 + 2 and 7 - 2)
Are the numbers 210 and 211 relatively prime?
Yes, 210 and 211 are relatively prime. Any numbers whose difference is 1 will only have 1 as a common factor, so they will be relatively prime.
What is the difference between the two largest two-digit prime numbers?
There can only be one largest two-digit prime number.
The only prime number that is the sum and difference of two prime numbers?
5. 2 + 3 = 5 7 - 2 = 5
What 2 prime numbers will give difference of one Is there another pair?
2 and 3 is the only pair.
