What are all of the twin prime numbers?
There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.
Do the prime factors of a number differ depending on which factors you choose first Explain?
No. It doesn't matter what factors you choose at the beginning, but all the factors should be prime at the end.
Can an Abundant number be a prime number?
No, all prime numbers are deficient.
Is a factor a prime number?
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
Is a prime number always an odd number?
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.
What are all the factor pairs of 101?
1 x 101 (101 is a prime number.)
What are all the fctor pairs of 83?
They are itself and 1 because 83 is a prime number

What are all the integer factor pairs for the number eleven?
11 is prime, so only 11 and 1
What are all the factor pairs of 2?
1 x 2, 2 x 1 (two is a prime number)
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?

It's a prime number so it only has one factor pair, 1•83
Does 25 have a twin prime?
25 is a composite number, not a prime. Twin primes are pairs of prime numbers that differ from each other by two. Examples of all twin primes less than 100 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
Is 27 a twin prime?
27 is a composite number, not a prime. Twin primes are pairs of prime numbers that differ from each other by two. Examples of all twin primes less than 100 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
What are the factor pairs of 639?
Separate the number into prime factors. Then it should be easy to get ALL the factors, simply by combining different prime factors.
How solve factorization?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
