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 23,406,385, 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 | 23,406,385 | |
| -1 | -23,406,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,406,385.
Example:
1 x 23,406,385 = 23,406,385
and
-1 x -23,406,385 = 23,406,385
Notice both answers equal 23,406,385
With that explanation out of the way, let's continue. Next, we take the number 23,406,385 and divide it by 2:
23,406,385 ÷ 2 = 11,703,192.5
If the quotient is a whole number, then 2 and 11,703,192.5 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 | 23,406,385 | |
| -1 | -23,406,385 |
Now, we try dividing 23,406,385 by 3:
23,406,385 ÷ 3 = 7,802,128.3333
If the quotient is a whole number, then 3 and 7,802,128.3333 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 | 23,406,385 | |
| -1 | -23,406,385 |
Let's try dividing by 4:
23,406,385 ÷ 4 = 5,851,596.25
If the quotient is a whole number, then 4 and 5,851,596.25 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 | 23,406,385 | |
| -1 | 23,406,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 6,659 | 33,295 | 126,521 | 246,383 | 632,605 | 1,231,915 | 4,681,277 | 23,406,385 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -6,659 | -33,295 | -126,521 | -246,383 | -632,605 | -1,231,915 | -4,681,277 | -23,406,385 |
