-3 + 3sqrt(6)i and -3 - 3sqrt(6)i.
Remember that i = sqrt(-1).
Even though negative numbers aren't usually considered factors of positive ones, you could use -9 and 3 or -7 and 1.
Negative numbers aren't really considered factors of positive ones, but you can use -28 and -3
There are none.
882 = 2 x 441 or 3 x 294 or 6 x 147 or 7 x 126 or 9 x 98 or 14 x 73 or 18 x 49 or 21 x 42
If you include negative numbers, use -14 and -18.
If that's -84, the answer is -21 and 4.
-8 and -3
20 and 30 All numbers have at least one common factor.
1 + 2 + 4 + 17 + 34 + 68 = 126
84 is one of 16 factors of 168.
Since 12 is a factor of 84, all of its factors are common.
The sum of the factors of any negative number is zero.
The factors of -84 that equal the sum of -16 are: -28 and 12 -14 and -2 -12 and -4
There are no such numbers. The only two numbers that sum to 12 and whose product is -84 are irrational, and so cannot be considered as factors of 84.
7 and 12
The sum is 144 if 60 is included, 84 if not.
1 + 5 + 13 + 65 = 84
-76
The factors of 68 are: 1, 2, 4, 17, 34, 68 The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
41 is prime, and 51 factors to 3 * 17. the factors of the sum is 7 and 13, the factors of the product are 41, 3 and 17.
The factor pairs of 84 are (84,1)(42,2)(28,3)(21,4)(14,6)(12,7) None of them add up to 17. If that was -84, you could use 21 and -4.
It is: 3+17 = 20
The sum of 622 and 84 is 706.
