A:
Positive:
1 x 706189147 x 15025397 x 728031549 x 4559
Negative:
-1 x -7061891-47 x -150253-97 x -72803-1549 x -4559
Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 7,061,891, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 7,061,891 | |
| -1 | -7,061,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,061,891.
Example:
1 x 7,061,891 = 7,061,891
and
-1 x -7,061,891 = 7,061,891
Notice both answers equal 7,061,891
With that explanation out of the way, let's continue. Next, we take the number 7,061,891 and divide it by 2:
7,061,891 ÷ 2 = 3,530,945.5
If the quotient is a whole number, then 2 and 3,530,945.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,061,891 | |
| -1 | -7,061,891 |
Now, we try dividing 7,061,891 by 3:
7,061,891 ÷ 3 = 2,353,963.6667
If the quotient is a whole number, then 3 and 2,353,963.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,061,891 | |
| -1 | -7,061,891 |
Let's try dividing by 4:
7,061,891 ÷ 4 = 1,765,472.75
If the quotient is a whole number, then 4 and 1,765,472.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,061,891 | |
| -1 | 7,061,891 |
If you did it right, you will end up with this table:
| 1 | 47 | 97 | 1,549 | 4,559 | 72,803 | 150,253 | 7,061,891 |
| -1 | -47 | -97 | -1,549 | -4,559 | -72,803 | -150,253 | -7,061,891 |
