-8
They are: 1+3+4 = 8 or 4+4 = 8
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
To find factors of 28 that add up to 18, we first list the factors of 28: 1, 2, 4, 7, 14, and 28. We then check pairs of these factors to see which add up to 18. The only pair that meets this criterion is 14 and 4, since 14 + 4 = 18. Thus, the factors of 28 that add up to 18 are 14 and 4.
The factor pairs of 80 are (80,1)(40,2)(20,4)(16,5)(10,8) None of them add up to -12.
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.
