Numbers called relatively prime have no common factors other than 1. All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
As an example, the factors of 14 are 1, 2, 7, and 14, and the factors of 15 are 1, 3, 5, and 15. 14 and 15 are relatively prime because the only factor they have in common is 1.
What else can I help you with?
Are two composite numbers always relatively prime?
No.
Is true that two composite numbers are relatively prime?
No it does not mean that.
If two numbers are relatively prime then one of them must be prime?
Not necessarily. 4 and 9 are relatively prime and both are composite.
What are 3 digit composite numbers which are relatively prime?
There are several ways to achieve this. For example, any two prime numbers. Or just multiply different small prime factors for each of the numbers - picking different prime factors for each - for example, a power of 2, and a power of 3.
Are the numbers 12 and 51 relatively prime?
Both numbers are composite because they have more than two factors
Are two composite numbers always relatively prime?
No.
Is true that two composite numbers are relatively prime?
No it does not mean that.
If two numbers are relatively prime then one of them must be prime?
Not necessarily. 4 and 9 are relatively prime and both are composite.
What conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
What are the least two composite numbers that are relatively prime?
120 and 49
Under what conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
Are two composite numbers may be relatively prime to each other?
Yes.
What are 3 digit composite numbers which are relatively prime?
There are several ways to achieve this. For example, any two prime numbers. Or just multiply different small prime factors for each of the numbers - picking different prime factors for each - for example, a power of 2, and a power of 3.
Is it true or false that two composite numbers are relatively prime and explain?
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.
Is the greatest common factor of two numbers a composite number?
The numbers are relatively prime, or co-prime.
Is the product of two prime numbers composite or prime?
The product of two prime numbers will be composite.
If two numbers do not have a common factor other than 1 what is it said to be?
Relatively prime or co-prime.
