A:
Positive:
1 x 122314997 x 174735753 x 230783371 x 32969
Negative:
-1 x -12231499-7 x -1747357-53 x -230783-371 x -32969
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 12,231,499, 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 | 12,231,499 | |
| -1 | -12,231,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,231,499.
Example:
1 x 12,231,499 = 12,231,499
and
-1 x -12,231,499 = 12,231,499
Notice both answers equal 12,231,499
With that explanation out of the way, let's continue. Next, we take the number 12,231,499 and divide it by 2:
12,231,499 ÷ 2 = 6,115,749.5
If the quotient is a whole number, then 2 and 6,115,749.5 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 | 12,231,499 | |
| -1 | -12,231,499 |
Now, we try dividing 12,231,499 by 3:
12,231,499 ÷ 3 = 4,077,166.3333
If the quotient is a whole number, then 3 and 4,077,166.3333 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 | 12,231,499 | |
| -1 | -12,231,499 |
Let's try dividing by 4:
12,231,499 ÷ 4 = 3,057,874.75
If the quotient is a whole number, then 4 and 3,057,874.75 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 | 12,231,499 | |
| -1 | 12,231,499 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 371 | 32,969 | 230,783 | 1,747,357 | 12,231,499 |
| -1 | -7 | -53 | -371 | -32,969 | -230,783 | -1,747,357 | -12,231,499 |
