A:
Positive:
1 x 55501397 x 79287743 x 129073301 x 18439
Negative:
-1 x -5550139-7 x -792877-43 x -129073-301 x -18439
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 5,550,139, 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 | 5,550,139 | |
| -1 | -5,550,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,550,139.
Example:
1 x 5,550,139 = 5,550,139
and
-1 x -5,550,139 = 5,550,139
Notice both answers equal 5,550,139
With that explanation out of the way, let's continue. Next, we take the number 5,550,139 and divide it by 2:
5,550,139 ÷ 2 = 2,775,069.5
If the quotient is a whole number, then 2 and 2,775,069.5 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 | 5,550,139 | |
| -1 | -5,550,139 |
Now, we try dividing 5,550,139 by 3:
5,550,139 ÷ 3 = 1,850,046.3333
If the quotient is a whole number, then 3 and 1,850,046.3333 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 | 5,550,139 | |
| -1 | -5,550,139 |
Let's try dividing by 4:
5,550,139 ÷ 4 = 1,387,534.75
If the quotient is a whole number, then 4 and 1,387,534.75 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 | 5,550,139 | |
| -1 | 5,550,139 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 18,439 | 129,073 | 792,877 | 5,550,139 |
| -1 | -7 | -43 | -301 | -18,439 | -129,073 | -792,877 | -5,550,139 |
