Here are some facts about prime numbers:
1. Prime numbers have exactly two factors - 1 and the Prime number itself.
2. The only even number that is prime is 2.
3. There are an infinite number of prime numbers.
4. Every number can be uniquely represented as a prime number or a product of prime numbers.
2 is prime
This is because they are only two factors in that number. It may seem to you that all prime numbers odd, but it is not true. Most of them however, are prime numbers. This is why most of the odd numbers are prime numbers.
False - 2 + 11 = 13.
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
No, prime numbers are only prime.
2 is prime
No, 2 is prime.
Any two prime numbers are relatively be prime?
Prime numbers can only be divided by themselves and 1.
No. It IS true that every whole number is either prime or composite. But there are numbers that are not whole numbers, such as 2.5, which are neither prime nor composite.
There are 25 prime numbers from 1 through 100.
Any two different prime numbers are relatively prime because relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor.
