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 23,307,425, 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 | 23,307,425 | |
| -1 | -23,307,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,307,425.
Example:
1 x 23,307,425 = 23,307,425
and
-1 x -23,307,425 = 23,307,425
Notice both answers equal 23,307,425
With that explanation out of the way, let's continue. Next, we take the number 23,307,425 and divide it by 2:
23,307,425 ÷ 2 = 11,653,712.5
If the quotient is a whole number, then 2 and 11,653,712.5 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 | 23,307,425 | |
| -1 | -23,307,425 |
Now, we try dividing 23,307,425 by 3:
23,307,425 ÷ 3 = 7,769,141.6667
If the quotient is a whole number, then 3 and 7,769,141.6667 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 | 23,307,425 | |
| -1 | -23,307,425 |
Let's try dividing by 4:
23,307,425 ÷ 4 = 5,826,856.25
If the quotient is a whole number, then 4 and 5,826,856.25 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 | 23,307,425 | |
| -1 | 23,307,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 173 | 317 | 425 | 865 | 1,585 | 2,941 | 4,325 | 5,389 | 7,925 | 14,705 | 26,945 | 54,841 | 73,525 | 134,725 | 274,205 | 932,297 | 1,371,025 | 4,661,485 | 23,307,425 |
| -1 | -5 | -17 | -25 | -85 | -173 | -317 | -425 | -865 | -1,585 | -2,941 | -4,325 | -5,389 | -7,925 | -14,705 | -26,945 | -54,841 | -73,525 | -134,725 | -274,205 | -932,297 | -1,371,025 | -4,661,485 | -23,307,425 |
