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.

No, prime numbers are only prime.

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.

Any two prime numbers are relatively be prime?

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.

It is true. Two numbers are relatively prime if they do not have any factors in common greater than 1. A prime number has only two factors - 1 and itself. Thus, two different prime numbers will only have 1 as a common factor, which means they are relatively prime.

No it is not. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

They are relatively prime, or co-prime.

false sometimes it contains 2 primes it always comes out to a prime number

All prime numbers are odd except for the number 2.

True(Prime factorization is to write a composite number as a product of its prime factors).

Since two primes obviously have no common factors greater than 1, you find the least common multiple by multiplying them together. This is true for any pair of numbers with no common factors greater than 1., not just prime numbers. Two numbers with no common factors greater than one are called relatively prime. For example, 8 and 9 are relatively prime even though both are composite numbers.
