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 23,305,535, 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 | 23,305,535 | |
| -1 | -23,305,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,305,535.
Example:
1 x 23,305,535 = 23,305,535
and
-1 x -23,305,535 = 23,305,535
Notice both answers equal 23,305,535
With that explanation out of the way, let's continue. Next, we take the number 23,305,535 and divide it by 2:
23,305,535 ÷ 2 = 11,652,767.5
If the quotient is a whole number, then 2 and 11,652,767.5 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 | 23,305,535 | |
| -1 | -23,305,535 |
Now, we try dividing 23,305,535 by 3:
23,305,535 ÷ 3 = 7,768,511.6667
If the quotient is a whole number, then 3 and 7,768,511.6667 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 | 23,305,535 | |
| -1 | -23,305,535 |
Let's try dividing by 4:
23,305,535 ÷ 4 = 5,826,383.75
If the quotient is a whole number, then 4 and 5,826,383.75 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 | 23,305,535 | |
| -1 | 23,305,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 643 | 659 | 3,215 | 3,295 | 7,073 | 7,249 | 35,365 | 36,245 | 423,737 | 2,118,685 | 4,661,107 | 23,305,535 |
| -1 | -5 | -11 | -55 | -643 | -659 | -3,215 | -3,295 | -7,073 | -7,249 | -35,365 | -36,245 | -423,737 | -2,118,685 | -4,661,107 | -23,305,535 |
