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 23,111,803, 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 | 23,111,803 | |
| -1 | -23,111,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,111,803.
Example:
1 x 23,111,803 = 23,111,803
and
-1 x -23,111,803 = 23,111,803
Notice both answers equal 23,111,803
With that explanation out of the way, let's continue. Next, we take the number 23,111,803 and divide it by 2:
23,111,803 ÷ 2 = 11,555,901.5
If the quotient is a whole number, then 2 and 11,555,901.5 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 | 23,111,803 | |
| -1 | -23,111,803 |
Now, we try dividing 23,111,803 by 3:
23,111,803 ÷ 3 = 7,703,934.3333
If the quotient is a whole number, then 3 and 7,703,934.3333 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 | 23,111,803 | |
| -1 | -23,111,803 |
Let's try dividing by 4:
23,111,803 ÷ 4 = 5,777,950.75
If the quotient is a whole number, then 4 and 5,777,950.75 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 | 23,111,803 | |
| -1 | 23,111,803 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 3,289 | 7,027 | 77,297 | 91,351 | 161,621 | 1,004,861 | 1,777,831 | 2,101,073 | 23,111,803 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -3,289 | -7,027 | -77,297 | -91,351 | -161,621 | -1,004,861 | -1,777,831 | -2,101,073 | -23,111,803 |
