Since 23 is a prime, the GCF is 1.
1, they have no common factors except 1
The factors of 17 are: 1, 17 The factors of 23 are: 1, 23 The common factors are: 1 The Greatest Common Factor: 1
The factors of 15 are: 1, 3, 5, 15The factors of 23 are: 1, 23
1, 23
The common factors of 23 are 1 and 23, as 23 is a prime number with only two factors. Therefore, the greatest common factor of 23 would be 23 itself, as it is the largest factor that both 1 and 23 have in common.
15 and 23 share no common factors aside from 1.
1 and 23 1 and 29 The only and therefore greatest common factor of 23 and 29 is 1.
The GCF of 15 and 23 is 1 because 23 is a prime and has no factors other than 1 and itself. 1, they have no common factors except 1 Using Euclid's Algorithm 23=(15)(1) + 8 => 15=(8)(1)+7 => 8=(7)(1)+1 => 7=(1)(7) Thus the highest common factor of 15 and 23 is 1.

The common factors are 1 and 3. The greatest of these is 3.
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 138 are 2, 3, and 23. The prime factors of 322 are 2, 7, and 23. The prime factors in common are 2 and 23, so the greatest common factor is 2 x 23 = 46.
