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 23,468,809, 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 | 23,468,809 | |
| -1 | -23,468,809 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,468,809.
Example:
1 x 23,468,809 = 23,468,809
and
-1 x -23,468,809 = 23,468,809
Notice both answers equal 23,468,809
With that explanation out of the way, let's continue. Next, we take the number 23,468,809 and divide it by 2:
23,468,809 ÷ 2 = 11,734,404.5
If the quotient is a whole number, then 2 and 11,734,404.5 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 | 23,468,809 | |
| -1 | -23,468,809 |
Now, we try dividing 23,468,809 by 3:
23,468,809 ÷ 3 = 7,822,936.3333
If the quotient is a whole number, then 3 and 7,822,936.3333 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 | 23,468,809 | |
| -1 | -23,468,809 |
Let's try dividing by 4:
23,468,809 ÷ 4 = 5,867,202.25
If the quotient is a whole number, then 4 and 5,867,202.25 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 | 23,468,809 | |
| -1 | 23,468,809 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 11,213 | 78,491 | 145,769 | 257,899 | 1,020,383 | 1,805,293 | 3,352,687 | 23,468,809 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -11,213 | -78,491 | -145,769 | -257,899 | -1,020,383 | -1,805,293 | -3,352,687 | -23,468,809 |
