The only common factor of 13 and 18 is 1 because they are co-prime.
The only common factor that 13 and 18 have is 1.One way to determine common factors is to find all the factors of the numbers and compare them.The factors of 13 are 1 and 13.The factors of 18 are 1, 2, 3, 6, 9, and 18.The only common factor is 1.Therefore, the least (smallest) common factor is 1 and the greatest (highest) common factor is 1.The least common factor of any set of integers is 1.
To find the common factors of 9 and 18, we first need to list the factors of each number. The factors of 9 are 1, 3, and 9, while the factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 9 and 18 are 1, 3, and 9. Adding these common factors together gives us a sum of 13.
The common factors of 13 and 39 are: 1 and 13
The GCF of 18 and 130 is 2. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 130 are 1, 2, 5, 10, 13, 26, 65, and 130. The common factors are 1 and 2, so 2 is the greatest common factor. You can also determine this by looking at the prime factors. The prime factors of 18 are 2, 3, and 3. The prime factors of 130 are 2, 5, and 13. The prime factors they have in common are a single 2, so 2 is their greatest common factor.
The common factors of 18 are: 1,2,3,6,9,18.
Since 13 is a factor of 39, all of its factors are common.
The factors of 18 are 1,2,3,6,9 and 18. For them to be common, they need to be compared to another set of factors.
The factors of 18 are 1,2,3,6,9 and 18. For them to be common, they need to be compared to another set of factors.
The factors of 13 are 1 and 13. For them to be common, they need to be compared to another set of factors.
Common factors of 6 and 18 are 1,2,3,6.
Factors of 26: 1, 2, 13, 26 Factors of 18: 1, 2, 3, 6, 9, 18 GCF (26, 18) = 2
Well, honey, the common factors of 13 and 26 are 1 and 13. That's it, plain and simple. Not much to work with there, but hey, at least you got your answer.
