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 173,513,165, 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 | 173,513,165 | |
| -1 | -173,513,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,513,165.
Example:
1 x 173,513,165 = 173,513,165
and
-1 x -173,513,165 = 173,513,165
Notice both answers equal 173,513,165
With that explanation out of the way, let's continue. Next, we take the number 173,513,165 and divide it by 2:
173,513,165 ÷ 2 = 86,756,582.5
If the quotient is a whole number, then 2 and 86,756,582.5 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 | 173,513,165 | |
| -1 | -173,513,165 |
Now, we try dividing 173,513,165 by 3:
173,513,165 ÷ 3 = 57,837,721.6667
If the quotient is a whole number, then 3 and 57,837,721.6667 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 | 173,513,165 | |
| -1 | -173,513,165 |
Let's try dividing by 4:
173,513,165 ÷ 4 = 43,378,291.25
If the quotient is a whole number, then 4 and 43,378,291.25 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 | 173,513,165 | |
| -1 | 173,513,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 49 | 185 | 245 | 259 | 1,295 | 1,813 | 9,065 | 19,141 | 95,705 | 133,987 | 669,935 | 708,217 | 937,909 | 3,541,085 | 4,689,545 | 4,957,519 | 24,787,595 | 34,702,633 | 173,513,165 |
| -1 | -5 | -7 | -35 | -37 | -49 | -185 | -245 | -259 | -1,295 | -1,813 | -9,065 | -19,141 | -95,705 | -133,987 | -669,935 | -708,217 | -937,909 | -3,541,085 | -4,689,545 | -4,957,519 | -24,787,595 | -34,702,633 | -173,513,165 |
