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 23,054,165, 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 | 23,054,165 | |
| -1 | -23,054,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,054,165.
Example:
1 x 23,054,165 = 23,054,165
and
-1 x -23,054,165 = 23,054,165
Notice both answers equal 23,054,165
With that explanation out of the way, let's continue. Next, we take the number 23,054,165 and divide it by 2:
23,054,165 ÷ 2 = 11,527,082.5
If the quotient is a whole number, then 2 and 11,527,082.5 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 | 23,054,165 | |
| -1 | -23,054,165 |
Now, we try dividing 23,054,165 by 3:
23,054,165 ÷ 3 = 7,684,721.6667
If the quotient is a whole number, then 3 and 7,684,721.6667 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 | 23,054,165 | |
| -1 | -23,054,165 |
Let's try dividing by 4:
23,054,165 ÷ 4 = 5,763,541.25
If the quotient is a whole number, then 4 and 5,763,541.25 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 | 23,054,165 | |
| -1 | 23,054,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 307 | 653 | 1,535 | 3,265 | 7,061 | 15,019 | 35,305 | 75,095 | 200,471 | 1,002,355 | 4,610,833 | 23,054,165 |
| -1 | -5 | -23 | -115 | -307 | -653 | -1,535 | -3,265 | -7,061 | -15,019 | -35,305 | -75,095 | -200,471 | -1,002,355 | -4,610,833 | -23,054,165 |
