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 23,020,459, 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 | 23,020,459 | |
| -1 | -23,020,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,020,459.
Example:
1 x 23,020,459 = 23,020,459
and
-1 x -23,020,459 = 23,020,459
Notice both answers equal 23,020,459
With that explanation out of the way, let's continue. Next, we take the number 23,020,459 and divide it by 2:
23,020,459 ÷ 2 = 11,510,229.5
If the quotient is a whole number, then 2 and 11,510,229.5 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 | 23,020,459 | |
| -1 | -23,020,459 |
Now, we try dividing 23,020,459 by 3:
23,020,459 ÷ 3 = 7,673,486.3333
If the quotient is a whole number, then 3 and 7,673,486.3333 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 | 23,020,459 | |
| -1 | -23,020,459 |
Let's try dividing by 4:
23,020,459 ÷ 4 = 5,755,114.75
If the quotient is a whole number, then 4 and 5,755,114.75 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 | 23,020,459 | |
| -1 | 23,020,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 6,361 | 44,527 | 69,971 | 298,967 | 489,797 | 2,092,769 | 3,288,637 | 23,020,459 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -6,361 | -44,527 | -69,971 | -298,967 | -489,797 | -2,092,769 | -3,288,637 | -23,020,459 |
