1 and 3, are both the common factors and the GCF of 15 and 27.
The GCF of 15 and 27 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 15 are 1, 3, 5, and 15. The factors of 27 are 1, 3, 9, and 27. The common factors are 1 and 3. Therefore, 3 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 15 are 3 and 5. The prime factors of 27 are 3, 3, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.
