The greatest common factor (GCF) of 9, 16, and 25 is 1 The factors of 9 are: 1, 3, 9 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 25 are: 1, 5, 25 The common factors are: 1 They're all squares of prime numbers

The only common factor of 16 and 25 is 1.

The GCF of 14 and 25 is 1. The factors of 14 are 1, 2, 7, and 14. The factors of 25 are 1, 5, and 25. The largest factor they have in common is 1, so 1 is the greatest common factor. This means they are relatively prime, since they have no factor in common other than 1. You can also determine the greatest common factor by their prime factors. The prime factors of 14 are 2 and 7. The prime factors of 25 are 5 and 5. They have no prime factors in common, which means they are relatively prime, so 1 is their greatest common factor. 1

5 is the only common prime factor.

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

Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.

The least common factor is: 1

The GCF is of 16 and 25 is 1.

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.

The Greatest Common Factor (GCF) is: 1

The greatest common factor of 25 and 72 is 1, so they are relatively prime.
