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 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.
The sum of 622 and 84 is 706.
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.
It is: 3+17 = 20
17% of 84= 17% * 84= 0.17 * 84= 14.28
