Numbers that have no common factor like 8 and 9 as 8=23 and 9=32 The two of them are not prime but they have no common factor

To be relatively prime, it would have to be compared to another number. When it is, if the GCF, or greatest common factor is 1, then it is relatively prime. 45 and 9 = NO because they have 9 in common. 45 and 31 = Yes because they only have 1 as a common factor.

9 is not a prime factor, but it does have one prime factor, which is three. Prime factors are factors of a number that are prime.

it is 9.

1 because 13 is a prime number.

All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.

Numbers that have no common factor like 8 and 9 as 8=23 and 9=32 The two of them are not prime but they have no common factor

Since 2 is a prime number, either it is the greatest common factor or 1 is. Since 2 is not a factor of 9, the greatest common factor is 1.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 2 are 1 and 2.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 2 is 2.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.Summary of results:The common factor is 1.The greatest common factor is 1.The numbers are relatively prime.The GCF is 1.The GCF is 1.

There is no common factor for 9 and 25 other than 1, so they are co-prime.

The greatest prime factor they have in common is 2.

The greatest common factor of 63, 81, and 99 is 9.The prime factorization of 63 is 7*9.The prime factorization of 81 is 9*9.The prime factorization of 99 is 11*9.Thus, the greatest of the common factors of 9.

The greatest common factor of 54 and 99 is 9, which is not prime. The greatest common factor of 80 and 114 is 2, which is prime.

The GCF of 9 and 26 is 1. 9 and 26 are relatively prime.

6 and 9

Answer:The greatest common factor of 7 and 9 is 1.The common factors of 7 and 9 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:The greatest common factor (gcf) of 7 and 9 is 1. This is because 7 is a prime number. Whenever one number is prime, if it is not a factor of the other number, the greatest common factor is 1.Another way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 7 are 1 and 7.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 7 is 7.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.1 because factors of 7 are 1,7 and factors of 9 are 1,9,3 and the largest factor they have in common is 1.The GCF is 1.

To be relatively prime, it would have to be compared to another number. When it is, if the GCF, or greatest common factor is 1, then it is relatively prime. 45 and 9 = NO because they have 9 in common. 45 and 31 = Yes because they only have 1 as a common factor.

The GCF of 9 and 20 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 20 are 1, 2, 4, 5, 10, and 20. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 9 are 3 and 3. The prime factors of 20 are 2, 2, and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1. Another way to approach this is to look at the difference between 9 and 20, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since 11 is a prime number, the greatest common factor must be either 1 or 11. The numbers 9 and 20 are not divisible by 11, so the greatest common factor must be 1.
