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 173,808,881, 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 | 173,808,881 | |
| -1 | -173,808,881 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,808,881.
Example:
1 x 173,808,881 = 173,808,881
and
-1 x -173,808,881 = 173,808,881
Notice both answers equal 173,808,881
With that explanation out of the way, let's continue. Next, we take the number 173,808,881 and divide it by 2:
173,808,881 ÷ 2 = 86,904,440.5
If the quotient is a whole number, then 2 and 86,904,440.5 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 | 173,808,881 | |
| -1 | -173,808,881 |
Now, we try dividing 173,808,881 by 3:
173,808,881 ÷ 3 = 57,936,293.6667
If the quotient is a whole number, then 3 and 57,936,293.6667 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 | 173,808,881 | |
| -1 | -173,808,881 |
Let's try dividing by 4:
173,808,881 ÷ 4 = 43,452,220.25
If the quotient is a whole number, then 4 and 43,452,220.25 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 | 173,808,881 | |
| -1 | 173,808,881 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 311 | 317 | 1,763 | 12,751 | 12,997 | 13,373 | 13,631 | 98,587 | 548,293 | 558,871 | 4,042,067 | 4,239,241 | 173,808,881 |
| -1 | -41 | -43 | -311 | -317 | -1,763 | -12,751 | -12,997 | -13,373 | -13,631 | -98,587 | -548,293 | -558,871 | -4,042,067 | -4,239,241 | -173,808,881 |
