Are 24 and 33 relatively prime?
No they are not. They have more than the number 1 as a common factor. They also have the number 3 as a common factor.
What is the gfc of 45 and 75?
GCF stands for Greatest Common Factor. This means that the GCF of 45 and 75 will be the greatest common factor of 45 and 75. The prime factorization of 45 is 3^2*5. Thus, a number is a factor of 45 if and only if it does not have more than 2 3s in its prime factorization, more than one 5 in its prime factorization, or any other prime factor. The prime factorization of 75 is 3*5^2. Thus, a number is a factor of 75 if and only if it does not have more than one 3 in its prime factorization, more than 2 5s in its prime factorization, or any other prime factor. Combining those two conclusions together, we get that if a number is a common factor of 45 and 75 if and only if it does not have more than one 3 in its prime factorization, more than one 5 in its prime factorization, or any other prime factor. Since multiplying by a 3 or a 5 will only increase the value of a number, there is no reason to not include them. Thus, the GCF of 45 and 75 is 3*5 or 15.
What is a factor that has 2 or more numbers?
A number that has only two factors is prime. A number that has more than two factors is composite.
Is 725 a prime number or a composite number?
725 is composite because it has more than 2 factors, not the "just the one and itself" factor thing that makes a number prime.
How do you get composite numbers by using prime factor?
A composite is any number that has a prime factor smaller than itself and greater than 1.
