The number four.
Pairs of numbers whose sum is -14 and that are factors of -189 include -7 and -7, and -21 and 7.
The factors of 21 are:1, 3, 7, 21The factors of 350 are:1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350The common factors are:1, 7
The sum of the factors of any negative number is zero.
the factors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126, so it has 12 factors

105 is the sum
105 is the sum
-14 and -21
You are 100.
21 and 5
100
21/100 plus 52/10 = 541/100 or 5.41
3 and 21.
Without just going and doing the addition, you can use this formula:Sum of 1 to N is: (N+1)*N/2. So take sum of [1 to 100], then subtract off the sum of [1 to 20], and you'll have left the sum [21 to 100].Sum [1-100] = (100+1)*100/2 = 5050. Sum[1-20] = (20+1)*20/2 = 210.So 5050 - 210 = 4840
30 and 70 Check: 30+70 = 100 and 30*70 = 2100
