1. Which isn't normally counted. 2 and 7 are mutually prime (they're also actually prime).
28 factors to [2 2 7] 36 factors to [2 2 3 3] Common factors are [2 2] Answer is 1, 2 and 4
The LCF of 4 & 7 is... 1 ! There are no other common factors.
The factors of 28 are: 1, 2, 4, 7, 14, 28The factors of 34 are: 1, 2, 17, 34The common factors are: 1, 2
The factors of 14 are: 1, 2, 7, 14The factors of 28 are: 1, 2, 4, 7, 14, 28The factors of 35 are: 1, 5, 7, 35The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7
There is neither a greatest common factor nor common factors of a single number, such as 52, 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 52 are 1, 2, 4, 13, 26, and 52. The prime factors of 52 are 2, 2, and 13. Examples: The common factors of 8 and 52 are 1, 2, and 4. The common factors of 39 and 52 are 1 and 13. The common factors of 52 and 78 are 1, 2, 13, and 26.
The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. The only common factor is 1.
28 factors to [2 2 7] 36 factors to [2 2 3 3] Common factors are [2 2] Answer is 1, 2 and 4
To find the common factors of 8 and 12, we first list the factors of each number. The factors of 8 are 1, 2, 4, and 8, while the factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors are 1, 2, and 4. To find the sum of these common factors, we add them together: 1 + 2 + 4 = 7. So, the sum of all the common factors of 8 and 12 is 7.
Factors of 4: 1, 2, 4 Factors of 7: 1, 7 GCF (4, 7) = 1
The common factors of 4 and 34 are 1 and 2
1 + 2 + 4 = 7
The factors of 14 are: 1, 2, 7, 14The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56The common factors are: 1, 2, 7, 14
The common factors of 28 and 70 are:28 factors are 1, 2, 4, 7, 14, 2870 factors are 1, 2, 5, 7, 10, 14, 35, 70So the common factors are 1, 2, 7, and 14
The common factors are: 1, 2, 4, 7, 14, 28
The common factors are: 1, 2, 4, 7, 14, 28
The common factors are: 1, 2, 4, 7, 14, 28.
The factors of 28 are: 1, 2, 4, 7, 14, 28.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The common factors are: 1, 2, 7, 14
