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 17,588,813, 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 | 17,588,813 | |
| -1 | -17,588,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,588,813.
Example:
1 x 17,588,813 = 17,588,813
and
-1 x -17,588,813 = 17,588,813
Notice both answers equal 17,588,813
With that explanation out of the way, let's continue. Next, we take the number 17,588,813 and divide it by 2:
17,588,813 ÷ 2 = 8,794,406.5
If the quotient is a whole number, then 2 and 8,794,406.5 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 | 17,588,813 | |
| -1 | -17,588,813 |
Now, we try dividing 17,588,813 by 3:
17,588,813 ÷ 3 = 5,862,937.6667
If the quotient is a whole number, then 3 and 5,862,937.6667 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 | 17,588,813 | |
| -1 | -17,588,813 |
Let's try dividing by 4:
17,588,813 ÷ 4 = 4,397,203.25
If the quotient is a whole number, then 4 and 4,397,203.25 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 | 17,588,813 | |
| -1 | 17,588,813 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 253 | 437 | 3,659 | 4,807 | 40,249 | 69,521 | 84,157 | 764,731 | 925,727 | 1,598,983 | 17,588,813 |
| -1 | -11 | -19 | -23 | -209 | -253 | -437 | -3,659 | -4,807 | -40,249 | -69,521 | -84,157 | -764,731 | -925,727 | -1,598,983 | -17,588,813 |
