BeauNo, 28 is not a common factor of 7 and 2. Factors of a number are integers that can be multiplied together to get that number. In this case, the factors of 7 are 1 and 7, and the factors of 2 are 1 and 2. Since 28 is not a factor of either 7 or 2, it is not a common factor of the two numbers.
CAREFUL! 28 is a common multiple of 7 and 2!
The common factors of 7 are:
1 x 7
-1 x -7
The common factors of 2 are:
1 x 2
-1 x -2
So, as you can see, the common factors of 7 and 2 are 1and -1

Highest common factor of 196 and 420?
196 = 2 x 2 x 7 x 7; 420 = 2 x 2 x 3 x 5 x 7. Common factors 2 x 2 x 7 ie 28 is the HCF.
What is the Highest common factor of 28 and 68?
To find the greatest common factor (GCF), first find the prime factorization of the two numbers. The GCF is the product of all of the prime factors the two numbers have in common. Prime factors of 28: 2, 2, 7 Prime factors of 68: 2, 2, 17 They have in common: 2, 2. 2x2=4 The GCF is 4.
What is the ratio of 28 and 8 in simplest form?
28:8 :: 7:2 ;; 3.5:1 NB note the use of colons, instead of writing out 'ratio to' all the time.
What is the GCF of 28 42 70?
The factors of 28 are:1, 2, 4, 7, 14, 28The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The factors of 70 are:1, 2, 5, 7, 10, 14, 35, 70The common factors are:1, 2, 7, 14The Greatest Common Factor (GCF) is: 14
Factor 7x to the 2nd power minus 28?
7(x - 2)(x + 2)
What is the common factor of 28 and126?
2, 7
What is the Greatest Common Factor of 42 35 and 28?
Greatest common factor= 7 The greatest common factor is the factor that all these numbers have in common. It helps to make a list of all the number's factors. 28- 2, 2, 7 35- 5, 7 42- 2, 3, 7 All of these numbers have 7 as a factor, therfore 7 is the greatest common factor
The greatest common factor for 7 and 28?
The greatest common factor of 7 and 28 is 7.
What is the greatest common factor of 28 and 7?
Since 7 is a factor of 28, it is automatically the GCF of 7 and 28The Greatest Common Factor (GCF) of 28 and 7 is 7.
What is the largest common factor of 28 and 42?
The common factors of 28 & 42 are : 2 , 7 , 14The largest common factor is 14
What is the least common factor of 14 and 28?
The factors of 14 are 1, 2, 7, and 14. The factors of 28 are 1, 2, 4, 7, 14, and 28. The common factors of 14 and 28 are 1, 2, 7, and 14. Therefore, the least (smallest) common factor is 1.
Common prime factor of 28 and 42?
2 and 7
What is the greatest common 7 and 28?
Since 7 is a factor of 28, it is automatically the GCF.
What is the greatest common factor of 28 and 77?
The greatest common factor of 28 and 77 is 7.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 28 are 1, 2, 4, 7, 14, and 28.The factors of 77 are 1, 7, 11, and 77.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 28 are 2, 2, and 7.The prime factors of 77 are 7 and 11.The prime factors in common are a single 7, so the greatest common factor is 7.Summary of results:The common factors are 1 and 7.The greatest common factor is 7.
What is the greatest common factor of 28 and 70?
14 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 28 are 2, 2, and 7. The prime factors of 70 are 2, 5, and 7. The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14.
What is the greatest common factor of 28 and 49?
The greatest common factor of 28 and 49 is 7.
What is the greatest common factor of 4 7 and 28?
The GCF of 4, 7, and 28 is 1.The prime factorization of 4 is 2*2.The prime factorization of 7 is 1*7.The prime factorization of 28 is 2*2*7.The have no common factor other than 1, so that is their GCF.
