The only proper factors of 77 are 7 and 11. 11 isn't a factor of 259 but 7 is, so the answer is 7.
Factors: 286=2*11*13 429=3*11*13 Common factors: 11, 13
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 44 are 1, 2, 4, 11, 22, and 44. The factors of 99 are 1, 3, 9, 11, 33, and 99. The common factors are 1 and 11. Therefore, the greatest common factor is 11. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 44 are 2, 2, and 11. The prime factors of 99 are 3, 3, and 11. The prime factors in common are a single 11, so the greatest common factor is 11. Answer: 11
7 and 12 share no common factors aside from 1.
The factors of 9 are:1, 3, 9The factors of 11 are:1, 11The common factor is:1
The common factors of 77 and 121 are 1 and 11.
The factors of 7 are:1, 7The factors of 8 are:1, 2, 4, 8The factors of 11 are:1, 11The common factor is:1

There are no common factors of 77 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. Examples: The common factors of 14 and 77 are 1 and 7. The common factors of 66 and 77 are 1 and 11. The common factors of 77 and 154 are 1, 7, 11, and 77.
Just 1.
Just 1
The factors of 7 are: 1 and 7The factors of 11 are: 1 and 11The greatest factor common to both is 1.
81 and 121 share no common factors aside from 1.
The factors of 88 are 1, 2, 4, 8, 11, 22, 44, and 88. The factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231. The common factors are 1 and 11. Therefore, the greatest common factor is 11. The greatest common factor can also be calculated by finding the prime factors and multiplying the common prime factors together. The prime factors of 88 are 2, 2, 2, and 11. The prime factors of 231 are 3, 7, and 11. The common prime factors are a single 11, so 11 is the greatest common factor.
As factors, just 1.
Common factors of 77 and 385 are: 1, 7, 11, and 77.
The factors of 22 are: 1, 2, 11, 22The factors of 77 are: 1, 7, 11, 77The common factors are: 1, 11Factors of 22 and 77 are 1 and 11. Since 22 x 1 = 22, 77 x 1 = 77 and 11 x 2 = 22, 11 x 7 = 77.
