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 11,712,835, 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 | 11,712,835 | |
| -1 | -11,712,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,712,835.
Example:
1 x 11,712,835 = 11,712,835
and
-1 x -11,712,835 = 11,712,835
Notice both answers equal 11,712,835
With that explanation out of the way, let's continue. Next, we take the number 11,712,835 and divide it by 2:
11,712,835 ÷ 2 = 5,856,417.5
If the quotient is a whole number, then 2 and 5,856,417.5 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 | 11,712,835 | |
| -1 | -11,712,835 |
Now, we try dividing 11,712,835 by 3:
11,712,835 ÷ 3 = 3,904,278.3333
If the quotient is a whole number, then 3 and 3,904,278.3333 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 | 11,712,835 | |
| -1 | -11,712,835 |
Let's try dividing by 4:
11,712,835 ÷ 4 = 2,928,208.75
If the quotient is a whole number, then 4 and 2,928,208.75 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 | 11,712,835 | |
| -1 | 11,712,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 139 | 695 | 887 | 2,641 | 4,435 | 13,205 | 16,853 | 84,265 | 123,293 | 616,465 | 2,342,567 | 11,712,835 |
| -1 | -5 | -19 | -95 | -139 | -695 | -887 | -2,641 | -4,435 | -13,205 | -16,853 | -84,265 | -123,293 | -616,465 | -2,342,567 | -11,712,835 |
