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 23,009,177, 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 | 23,009,177 | |
| -1 | -23,009,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,009,177.
Example:
1 x 23,009,177 = 23,009,177
and
-1 x -23,009,177 = 23,009,177
Notice both answers equal 23,009,177
With that explanation out of the way, let's continue. Next, we take the number 23,009,177 and divide it by 2:
23,009,177 ÷ 2 = 11,504,588.5
If the quotient is a whole number, then 2 and 11,504,588.5 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 | 23,009,177 | |
| -1 | -23,009,177 |
Now, we try dividing 23,009,177 by 3:
23,009,177 ÷ 3 = 7,669,725.6667
If the quotient is a whole number, then 3 and 7,669,725.6667 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 | 23,009,177 | |
| -1 | -23,009,177 |
Let's try dividing by 4:
23,009,177 ÷ 4 = 5,752,294.25
If the quotient is a whole number, then 4 and 5,752,294.25 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 | 23,009,177 | |
| -1 | 23,009,177 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 83 | 391 | 709 | 1,411 | 1,909 | 12,053 | 16,307 | 32,453 | 58,847 | 277,219 | 1,000,399 | 1,353,481 | 23,009,177 |
| -1 | -17 | -23 | -83 | -391 | -709 | -1,411 | -1,909 | -12,053 | -16,307 | -32,453 | -58,847 | -277,219 | -1,000,399 | -1,353,481 | -23,009,177 |
