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 173,580,827, 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 | 173,580,827 | |
| -1 | -173,580,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,580,827.
Example:
1 x 173,580,827 = 173,580,827
and
-1 x -173,580,827 = 173,580,827
Notice both answers equal 173,580,827
With that explanation out of the way, let's continue. Next, we take the number 173,580,827 and divide it by 2:
173,580,827 ÷ 2 = 86,790,413.5
If the quotient is a whole number, then 2 and 86,790,413.5 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 | 173,580,827 | |
| -1 | -173,580,827 |
Now, we try dividing 173,580,827 by 3:
173,580,827 ÷ 3 = 57,860,275.6667
If the quotient is a whole number, then 3 and 57,860,275.6667 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 | 173,580,827 | |
| -1 | -173,580,827 |
Let's try dividing by 4:
173,580,827 ÷ 4 = 43,395,206.75
If the quotient is a whole number, then 4 and 43,395,206.75 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 | 173,580,827 | |
| -1 | 173,580,827 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 409 | 2,863 | 3,191 | 7,771 | 22,337 | 54,397 | 60,629 | 424,403 | 1,305,119 | 9,135,833 | 24,797,261 | 173,580,827 |
| -1 | -7 | -19 | -133 | -409 | -2,863 | -3,191 | -7,771 | -22,337 | -54,397 | -60,629 | -424,403 | -1,305,119 | -9,135,833 | -24,797,261 | -173,580,827 |
