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 173,025,655, 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 | 173,025,655 | |
| -1 | -173,025,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,025,655.
Example:
1 x 173,025,655 = 173,025,655
and
-1 x -173,025,655 = 173,025,655
Notice both answers equal 173,025,655
With that explanation out of the way, let's continue. Next, we take the number 173,025,655 and divide it by 2:
173,025,655 ÷ 2 = 86,512,827.5
If the quotient is a whole number, then 2 and 86,512,827.5 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 | 173,025,655 | |
| -1 | -173,025,655 |
Now, we try dividing 173,025,655 by 3:
173,025,655 ÷ 3 = 57,675,218.3333
If the quotient is a whole number, then 3 and 57,675,218.3333 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 | 173,025,655 | |
| -1 | -173,025,655 |
Let's try dividing by 4:
173,025,655 ÷ 4 = 43,256,413.75
If the quotient is a whole number, then 4 and 43,256,413.75 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 | 173,025,655 | |
| -1 | 173,025,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 59,357 | 296,785 | 652,927 | 3,145,921 | 3,264,635 | 15,729,605 | 34,605,131 | 173,025,655 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -59,357 | -296,785 | -652,927 | -3,145,921 | -3,264,635 | -15,729,605 | -34,605,131 | -173,025,655 |
