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 23,711,435, 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 | 23,711,435 | |
| -1 | -23,711,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,711,435.
Example:
1 x 23,711,435 = 23,711,435
and
-1 x -23,711,435 = 23,711,435
Notice both answers equal 23,711,435
With that explanation out of the way, let's continue. Next, we take the number 23,711,435 and divide it by 2:
23,711,435 ÷ 2 = 11,855,717.5
If the quotient is a whole number, then 2 and 11,855,717.5 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 | 23,711,435 | |
| -1 | -23,711,435 |
Now, we try dividing 23,711,435 by 3:
23,711,435 ÷ 3 = 7,903,811.6667
If the quotient is a whole number, then 3 and 7,903,811.6667 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 | 23,711,435 | |
| -1 | -23,711,435 |
Let's try dividing by 4:
23,711,435 ÷ 4 = 5,927,858.75
If the quotient is a whole number, then 4 and 5,927,858.75 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 | 23,711,435 | |
| -1 | 23,711,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 13,907 | 69,535 | 152,977 | 431,117 | 764,885 | 2,155,585 | 4,742,287 | 23,711,435 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -13,907 | -69,535 | -152,977 | -431,117 | -764,885 | -2,155,585 | -4,742,287 | -23,711,435 |
