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 9,126,377, 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 | 9,126,377 | |
| -1 | -9,126,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,126,377.
Example:
1 x 9,126,377 = 9,126,377
and
-1 x -9,126,377 = 9,126,377
Notice both answers equal 9,126,377
With that explanation out of the way, let's continue. Next, we take the number 9,126,377 and divide it by 2:
9,126,377 ÷ 2 = 4,563,188.5
If the quotient is a whole number, then 2 and 4,563,188.5 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 | 9,126,377 | |
| -1 | -9,126,377 |
Now, we try dividing 9,126,377 by 3:
9,126,377 ÷ 3 = 3,042,125.6667
If the quotient is a whole number, then 3 and 3,042,125.6667 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 | 9,126,377 | |
| -1 | -9,126,377 |
Let's try dividing by 4:
9,126,377 ÷ 4 = 2,281,594.25
If the quotient is a whole number, then 4 and 2,281,594.25 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 | 9,126,377 | |
| -1 | 9,126,377 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 131 | 233 | 299 | 1,703 | 3,013 | 3,029 | 5,359 | 30,523 | 39,169 | 69,667 | 396,799 | 702,029 | 9,126,377 |
| -1 | -13 | -23 | -131 | -233 | -299 | -1,703 | -3,013 | -3,029 | -5,359 | -30,523 | -39,169 | -69,667 | -396,799 | -702,029 | -9,126,377 |
