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 172,753,375, 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 | 172,753,375 | |
| -1 | -172,753,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,753,375.
Example:
1 x 172,753,375 = 172,753,375
and
-1 x -172,753,375 = 172,753,375
Notice both answers equal 172,753,375
With that explanation out of the way, let's continue. Next, we take the number 172,753,375 and divide it by 2:
172,753,375 ÷ 2 = 86,376,687.5
If the quotient is a whole number, then 2 and 86,376,687.5 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 | 172,753,375 | |
| -1 | -172,753,375 |
Now, we try dividing 172,753,375 by 3:
172,753,375 ÷ 3 = 57,584,458.3333
If the quotient is a whole number, then 3 and 57,584,458.3333 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 | 172,753,375 | |
| -1 | -172,753,375 |
Let's try dividing by 4:
172,753,375 ÷ 4 = 43,188,343.75
If the quotient is a whole number, then 4 and 43,188,343.75 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 | 172,753,375 | |
| -1 | 172,753,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 727 | 1,901 | 3,635 | 9,505 | 18,175 | 47,525 | 90,875 | 237,625 | 1,382,027 | 6,910,135 | 34,550,675 | 172,753,375 |
| -1 | -5 | -25 | -125 | -727 | -1,901 | -3,635 | -9,505 | -18,175 | -47,525 | -90,875 | -237,625 | -1,382,027 | -6,910,135 | -34,550,675 | -172,753,375 |
