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 171,083,875, 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 | 171,083,875 | |
| -1 | -171,083,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,083,875.
Example:
1 x 171,083,875 = 171,083,875
and
-1 x -171,083,875 = 171,083,875
Notice both answers equal 171,083,875
With that explanation out of the way, let's continue. Next, we take the number 171,083,875 and divide it by 2:
171,083,875 ÷ 2 = 85,541,937.5
If the quotient is a whole number, then 2 and 85,541,937.5 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 | 171,083,875 | |
| -1 | -171,083,875 |
Now, we try dividing 171,083,875 by 3:
171,083,875 ÷ 3 = 57,027,958.3333
If the quotient is a whole number, then 3 and 57,027,958.3333 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 | 171,083,875 | |
| -1 | -171,083,875 |
Let's try dividing by 4:
171,083,875 ÷ 4 = 42,770,968.75
If the quotient is a whole number, then 4 and 42,770,968.75 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 | 171,083,875 | |
| -1 | 171,083,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 421 | 2,105 | 3,251 | 10,525 | 16,255 | 52,625 | 81,275 | 406,375 | 1,368,671 | 6,843,355 | 34,216,775 | 171,083,875 |
| -1 | -5 | -25 | -125 | -421 | -2,105 | -3,251 | -10,525 | -16,255 | -52,625 | -81,275 | -406,375 | -1,368,671 | -6,843,355 | -34,216,775 | -171,083,875 |
