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 23,331,745, 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 | 23,331,745 | |
| -1 | -23,331,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,331,745.
Example:
1 x 23,331,745 = 23,331,745
and
-1 x -23,331,745 = 23,331,745
Notice both answers equal 23,331,745
With that explanation out of the way, let's continue. Next, we take the number 23,331,745 and divide it by 2:
23,331,745 ÷ 2 = 11,665,872.5
If the quotient is a whole number, then 2 and 11,665,872.5 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 | 23,331,745 | |
| -1 | -23,331,745 |
Now, we try dividing 23,331,745 by 3:
23,331,745 ÷ 3 = 7,777,248.3333
If the quotient is a whole number, then 3 and 7,777,248.3333 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 | 23,331,745 | |
| -1 | -23,331,745 |
Let's try dividing by 4:
23,331,745 ÷ 4 = 5,832,936.25
If the quotient is a whole number, then 4 and 5,832,936.25 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 | 23,331,745 | |
| -1 | 23,331,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 257 | 271 | 335 | 1,285 | 1,355 | 17,219 | 18,157 | 69,647 | 86,095 | 90,785 | 348,235 | 4,666,349 | 23,331,745 |
| -1 | -5 | -67 | -257 | -271 | -335 | -1,285 | -1,355 | -17,219 | -18,157 | -69,647 | -86,095 | -90,785 | -348,235 | -4,666,349 | -23,331,745 |
