The GCF is 1.
The factors of 15 are: 1, 3, 5, 15.The factors of 39 are: 1, 3, 13, 39.The common factors are: 1, 3.
One is the only common factor of 8 9 13 and 15?
1 is a common factor of 11, 12, 13, 14 and 15.
No. 11 and 13 are factors of 143, 15 has no relation.
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.
Six.
The GCF of 15 and 65 is 5. 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 65 are 1, 5, 13, and 65. The common factors are 1 and 5. Therefore, the greatest common factor is 5. 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 65 are 5 and 13. The common prime factors are a single 5, so the greatest common factor is 5.
The factors of 13 are 1 and 13. (It is prime)The factors of 15 are 1, 3, 5, and 15.
The factors of 15 are:1, 3, 5, 15The factors of 65 are:1, 5, 13, 65The common factors are:1, 5The Greatest Common Factor (GCF) is:5
13 is prime, so it's factors are 1 & 13. 15 = 1 * 3 * 5, so 1 is the only common factor.
The factors of 15 are:1, 3, 5, 15The factors of 39 are:1, 3, 13, 39The common factors are:1, 3The Greatest Common Factor (GCF) is:3
There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
