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 23,003,045, 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 | 23,003,045 | |
| -1 | -23,003,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,003,045.
Example:
1 x 23,003,045 = 23,003,045
and
-1 x -23,003,045 = 23,003,045
Notice both answers equal 23,003,045
With that explanation out of the way, let's continue. Next, we take the number 23,003,045 and divide it by 2:
23,003,045 ÷ 2 = 11,501,522.5
If the quotient is a whole number, then 2 and 11,501,522.5 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 | 23,003,045 | |
| -1 | -23,003,045 |
Now, we try dividing 23,003,045 by 3:
23,003,045 ÷ 3 = 7,667,681.6667
If the quotient is a whole number, then 3 and 7,667,681.6667 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 | 23,003,045 | |
| -1 | -23,003,045 |
Let's try dividing by 4:
23,003,045 ÷ 4 = 5,750,761.25
If the quotient is a whole number, then 4 and 5,750,761.25 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 | 23,003,045 | |
| -1 | 23,003,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 227 | 1,135 | 1,559 | 2,951 | 7,795 | 14,755 | 20,267 | 101,335 | 353,893 | 1,769,465 | 4,600,609 | 23,003,045 |
| -1 | -5 | -13 | -65 | -227 | -1,135 | -1,559 | -2,951 | -7,795 | -14,755 | -20,267 | -101,335 | -353,893 | -1,769,465 | -4,600,609 | -23,003,045 |
