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 172,712,755, 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 | 172,712,755 | |
| -1 | -172,712,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,712,755.
Example:
1 x 172,712,755 = 172,712,755
and
-1 x -172,712,755 = 172,712,755
Notice both answers equal 172,712,755
With that explanation out of the way, let's continue. Next, we take the number 172,712,755 and divide it by 2:
172,712,755 ÷ 2 = 86,356,377.5
If the quotient is a whole number, then 2 and 86,356,377.5 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 | 172,712,755 | |
| -1 | -172,712,755 |
Now, we try dividing 172,712,755 by 3:
172,712,755 ÷ 3 = 57,570,918.3333
If the quotient is a whole number, then 3 and 57,570,918.3333 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 | 172,712,755 | |
| -1 | -172,712,755 |
Let's try dividing by 4:
172,712,755 ÷ 4 = 43,178,188.75
If the quotient is a whole number, then 4 and 43,178,188.75 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 | 172,712,755 | |
| -1 | 172,712,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 761 | 2,389 | 3,805 | 11,945 | 14,459 | 45,391 | 72,295 | 226,955 | 1,818,029 | 9,090,145 | 34,542,551 | 172,712,755 |
| -1 | -5 | -19 | -95 | -761 | -2,389 | -3,805 | -11,945 | -14,459 | -45,391 | -72,295 | -226,955 | -1,818,029 | -9,090,145 | -34,542,551 | -172,712,755 |
