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 23,440,535, 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 | 23,440,535 | |
| -1 | -23,440,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,440,535.
Example:
1 x 23,440,535 = 23,440,535
and
-1 x -23,440,535 = 23,440,535
Notice both answers equal 23,440,535
With that explanation out of the way, let's continue. Next, we take the number 23,440,535 and divide it by 2:
23,440,535 ÷ 2 = 11,720,267.5
If the quotient is a whole number, then 2 and 11,720,267.5 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 | 23,440,535 | |
| -1 | -23,440,535 |
Now, we try dividing 23,440,535 by 3:
23,440,535 ÷ 3 = 7,813,511.6667
If the quotient is a whole number, then 3 and 7,813,511.6667 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 | 23,440,535 | |
| -1 | -23,440,535 |
Let's try dividing by 4:
23,440,535 ÷ 4 = 5,860,133.75
If the quotient is a whole number, then 4 and 5,860,133.75 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 | 23,440,535 | |
| -1 | 23,440,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 485 | 1,649 | 2,843 | 8,245 | 14,215 | 48,331 | 241,655 | 275,771 | 1,378,855 | 4,688,107 | 23,440,535 |
| -1 | -5 | -17 | -85 | -97 | -485 | -1,649 | -2,843 | -8,245 | -14,215 | -48,331 | -241,655 | -275,771 | -1,378,855 | -4,688,107 | -23,440,535 |
