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 common factors of 26 and 52 are: 1, 2, 13, and 26
The 4 factors of 26 are 1, 2, 13, and 26.The factor pairs of 26 are 1 x 26 and 2 x 13.The proper factors of 26 are 1, 2, and 13 or,if the definition you are using excludes 1, they are 2 and 13.The prime factors of 26 are 2 and 13.The 2 distinct prime factors (listing each prime factor only once) of 26 are 2 and 13.The prime factorization of 26 is 2 x 13.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
The common factors are: 1, 2, 13, 26.
There are none.
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.
The factors of 26 are:1, 2, 13, 26The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are:1, 2
The factors of 91 are:1, 7, 13, 91The factors of 156 are:1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156The common factors are:1, 13
The common factors of 13 and 39 are: 1 and 13
