One is the only common factor of 8 9 13 and 15?
gcf(15, 13, 25) = 1.
The least common factor of any set of integers is 1.
1 is a common factor of 11, 12, 13, 14 and 15.
The GCF is 1.
The least common factor of any set of integers is 1.
The least common factor of any set of numbers is 1.
1
The GCF is 1.
15 = 3 x 5 65 = 5 x 13 So the greatest common factor is 5
The factors of 15 are 1, 3, 5, and 15. The factors of 39 are 1, 3, 13, and 39. The factors they have in common are 1 and 3. Therefore, the greatest common factor is 3. You can also determine the greatest common factor from their prime factors. The prime factors of 15 are 3 and 5. The prime factors of 39 are 3 and 13. The prime factors they have in common are a single 3, so the greatest common factor is 3.
They only have a common factor of one(1), so the product of 13 & 15 is the same as the LCM. 195
