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 10,115,561, 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 | 10,115,561 | |
| -1 | -10,115,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,115,561.
Example:
1 x 10,115,561 = 10,115,561
and
-1 x -10,115,561 = 10,115,561
Notice both answers equal 10,115,561
With that explanation out of the way, let's continue. Next, we take the number 10,115,561 and divide it by 2:
10,115,561 ÷ 2 = 5,057,780.5
If the quotient is a whole number, then 2 and 5,057,780.5 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 | 10,115,561 | |
| -1 | -10,115,561 |
Now, we try dividing 10,115,561 by 3:
10,115,561 ÷ 3 = 3,371,853.6667
If the quotient is a whole number, then 3 and 3,371,853.6667 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 | 10,115,561 | |
| -1 | -10,115,561 |
Let's try dividing by 4:
10,115,561 ÷ 4 = 2,528,890.25
If the quotient is a whole number, then 4 and 2,528,890.25 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 | 10,115,561 | |
| -1 | 10,115,561 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 41 | 391 | 631 | 697 | 943 | 10,727 | 14,513 | 16,031 | 25,871 | 246,721 | 439,807 | 595,033 | 10,115,561 |
| -1 | -17 | -23 | -41 | -391 | -631 | -697 | -943 | -10,727 | -14,513 | -16,031 | -25,871 | -246,721 | -439,807 | -595,033 | -10,115,561 |
