13 is a Prime number. The only common factors are 1 and 13.
Since 13 is a factor of 39, all of its factors are common.
The common factors of 13 and 39 are: 1 and 13
The GCF of 143 and 169 is 13. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 143 are 1, 11, 13, and 143. The factors of 169 are 1, 13, and 169. The common factors are 1 and 13. Therefore, the greatest common factor is 13.
The factors of 26 are 26, 13, 2 and 1
The factors of 13 are 1 and 13. For them to be common, they need to be compared to another set of factors.
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.
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.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 13, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 13 are 1 and 13. Examples: The common factors of 13 and 25 are only 1; the greatest common factor is 1. The common factors of 13 and 52 are 1 and 13; the greatest common factor is 13.
The greatest common factor of 13 and 51 is 1.The common factors of 13 and 51 are only the number 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 13 are 1 and 13.The factors of 51 are 1, 3, 17, and 51.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 13 are 1 and 13.The prime factors of 51 are 3 and 17.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
Six.
13 and 53 share no common factors aside from 1.
