What else can I help you with?
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.
Julia says that prime numbers have to be odd and composite numbers have to be even. is she correct explain how you know?
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.
How do you find out how numbers are relatively prime?
Two numbers are relatively prime if their GCF is 1.
Are any two prime numbers relatively prime?
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.
How many numbers are relatively prime to 37?
Infinitely many numbers are relatively prime to 37. Because 37 is a prime number, all other numbers are relatively prime to it.
Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement?
The numbers are not relatively prime, because they have a common factor of 2. To simplify, any pair is relatively prime, if their GCD is 1. In this case, GCD(38,40) = 2 which is not equal to 1, thus, they are not relatively prime.
Does composite numbers have an even number of factors correct or incorrect explain?
Incorrect. Square numbers are composite and have an odd number of factors.
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.
Julia says that prime numbers have to be odd and composite numbers have to be even. is she correct explain how you know?
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.
Explain why 4-chloro-3methylbutane is the incorrect name?
When naming a compound, you should use the lowest numbers you can, so it should be called 1-chloro-2-methylbutane.
How do you find out how numbers are relatively prime?
Two numbers are relatively prime if their GCF is 1.
What are related prime numbers?
You might be thinking of relatively prime numbers. Two numbers are considered relatively prime if their GCF is 1. 4 and 9 are relatively prime.
Are any two prime numbers relatively prime?
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.
What mean relatively prime numbers?
Two numbers are considered relatively prime when their GCF is 1.
How is the LCM related to the relatively prime numbers?
When two numbers are relatively prime, the LCM will be their product.
How many numbers are relatively prime to 37?
Infinitely many numbers are relatively prime to 37. Because 37 is a prime number, all other numbers are relatively prime to it.
Is 2 relatively prime?
For relatively prime numbers to exist, there need to be two or more numbers to compare.
