The greatest common factor of two or more prime numbers is 1.

If the greatest common factor is 1, then the numbers are said to be co-prime or relatively prime.

Prime numbers and numbers that are relatively prime.

Because both numbers are prime numbers, the only common factor they have is 1. Therefore, 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 5 are 1 and 5. The factors of 23 are 1 and 23. 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 5 is 5. The prime factor of 23 is 23. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

A prime number

The greatest common factor of two different prime numbers is 1. The two prime numbers have as their factors, 1 and themselves. That means that 1 is the only factor they have in common.The GCF is 1.

The numbers are relatively prime, or co-prime.

Yes, the greatest common factor of two different prime numbers is always 1

Since they are both prime numbers - the greatest common factor is 1 !

No.

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.

19 and 13 are prime numbers. Therefore, the greatest common factor is 1.

The greatest common factor of 53 and 71 is 1. Both numbers are prime.

The greatest common factor of 49 and 32 is 1. The numbers are co-prime.

Any two or more prime numbers have 1 as the greatest common factor.

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.

Several numbers have the greatest common factor of 1. These numbers are often called prime numbers. Their only factors are 1 and themselves.

As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.

They are co-prime.

They are relatively prime, or co-prime.

yes

That would be 1

The numbers are co-prime.
