The GCF is: 1
13 is a prime number & 27 = 3*3*3*1, so the greatest common factor of 13 and 27 would be 1, which is the only common factor.
The GCF of 13 and 24 is 1.The GCF is 1.
The answer to this problem is simple, the Greatest Common Factor (GCF) is 27.
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.
The GCF is 1.
The GCF is 3.
The GCF of 39 and 65 is 13. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 39 are 1, 3, 13, and 39. The factors of 65 are 1, 5, 13, and 65. The common factors are 1 and 13. Therefore, the greatest common factor is 13. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 39 are 3 and 13. The prime factors of 65 are 5 and 13. The prime factors in common are a single 13, so the greatest common factor is 13.
The GCF of 39 and 52 is 13 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 39 are 1, 3, 13, and 39. The factors of 52 are 1, 2, 4, 13, 26, and 52. The common factors are 1 and 13. Therefore, the greatest common factor is 13. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 39 are 3 and 13. The prime factors of 52 are 2, 2, and 13. The prime factors in common are a single 13, so the greatest common factor is 13.
13 2*13 = 26 3*13 = 39
Factor them. 2 x 13 = 26 3 x 13 = 39 Select the common factor. The GCF is 13.
The greatest common factor of 30 and 39 is 3.
15 = 3 x 5 65 = 5 x 13 So the greatest common factor is 5
