2 x 2 x 2 x 2 x 3 = 48
2 x 2 x 2 x 2 x 5 = 80
2 x 2 x 2 x 2 = 16, the GCF

What is the greatest common factor of 289 and 589?
1 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 289 are 1, 17, and 289. The factors of 589 are 1, 19, 31, and 589. The common factors are 1. Therefore, the greatest common factor is 1; they 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 289 are 17 and 17. The prime factors of 589 are 19 and 31. There are no prime factors in common, which means they are relatively prime, so the greatest common factor is 1.
What is the greatest common factor of 173?
Two (or more) integers have a common factor - e.g., the greatest common factor of 173 and 100 is 1, or the greatest common factor of 173 and 519 is 173. The question makes no sense with one number. 173 is a prime, by the way.
What is the greatest common factor of relatively prime numbers?
The GCF is 1.
Which number is greatest factor of every number?
The greatest factor of any number is the number itself. There is no integer that is the greatest factor of every number. One is a factor of every number. One is the GCF of co-prime numbers.
Is the greatest common factor of two different prime numbers always one?
Yes, that is correct.
What is the greatest common factor of 19 and 13?
19 and 13 are prime numbers. Therefore, the greatest common factor is 1.
What are two numbers if their greatest common factor is one?
They are co-prime.
What is the greatest common factor of 2 and 211?
The only factors of 2 are 1 and 2, so the greatest common factor is 2 if the other number is even or 1 if it is not. 211 is not even. Therefore, the greatest common factor is 1. Another way to solve this is by knowing that when both numbers are prime numbers, the greatest common factor is 1. Both 2 and 211 are prime numbers, so their greatest common factor is 1. One more 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 211 are 1 and 211. 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 2 is 2. The prime factor of 211 is 211. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
If the greatest common factor of two numbers is one what can you say about the number?
The numbers are relatively prime, or co-prime.
What is the greatest common factor of 37 and 81?
The factors of 37 are 1 and 37. The factors of 81 are 1, 3, 9, 27, and 81. They have only one factor in common - 1. Since the greatest common factor of 37 and 81 is 1, they are relatively prime. You can also look at the prime factors to determine the greatest common factor. 37 is a prime number, so its only prime factor is itself, 37. The prime factors of 81 are 3, 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their greatest common factor is 1.
What is the greatest common factor of 12 and 25?
The greatest common factor of 12 and 25 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 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 25. The only common factor is 1. Therefore, the greatest common factor is 1. 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 12 are 2, 2, and 3. The prime factors of 25 are 5 and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is the greatest common factor of 65 and 213?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 65 are 1, 5, 13, and 65. The factors of 213 are 1, 3, 71, and 213. 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 65 are 5 and 13. The prime factors of 213 are 3 and 71. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is the greatest common factor of 4 and 33?
The greatest common factor of 33 and 4 is 1. This is because 33 and 4 are prime to each other, that is; they only have one factor in common, 1.
Why is the greatest common factor of 17 and 23 is 1?
17 and 23 are both prime. The only factors they have are one and themselves. Their only factor in common is 1 so it has to be the greatest common factor.
What is the greatest common factor of 289 and 589?
1 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 289 are 1, 17, and 289. The factors of 589 are 1, 19, 31, and 589. The common factors are 1. Therefore, the greatest common factor is 1; they 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 289 are 17 and 17. The prime factors of 589 are 19 and 31. There are no prime factors in common, which means they are relatively prime, so the greatest common factor is 1.
Greatest common factor of 30 and 49?
The greatest common factor of 30 and 49 is 1. This is because 30 and 49 are prime to each other;that is, they only have one factor common to both of them. And that factor is 1.
What is the greatest common factor of 173?
Two (or more) integers have a common factor - e.g., the greatest common factor of 173 and 100 is 1, or the greatest common factor of 173 and 519 is 173. The question makes no sense with one number. 173 is a prime, by the way.
