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 23,024,545, 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 | 23,024,545 | |
| -1 | -23,024,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,024,545.
Example:
1 x 23,024,545 = 23,024,545
and
-1 x -23,024,545 = 23,024,545
Notice both answers equal 23,024,545
With that explanation out of the way, let's continue. Next, we take the number 23,024,545 and divide it by 2:
23,024,545 ÷ 2 = 11,512,272.5
If the quotient is a whole number, then 2 and 11,512,272.5 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 | 23,024,545 | |
| -1 | -23,024,545 |
Now, we try dividing 23,024,545 by 3:
23,024,545 ÷ 3 = 7,674,848.3333
If the quotient is a whole number, then 3 and 7,674,848.3333 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 | 23,024,545 | |
| -1 | -23,024,545 |
Let's try dividing by 4:
23,024,545 ÷ 4 = 5,756,136.25
If the quotient is a whole number, then 4 and 5,756,136.25 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 | 23,024,545 | |
| -1 | 23,024,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 7,321 | 36,605 | 124,457 | 270,877 | 622,285 | 1,354,385 | 4,604,909 | 23,024,545 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -7,321 | -36,605 | -124,457 | -270,877 | -622,285 | -1,354,385 | -4,604,909 | -23,024,545 |
