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 173,417,705, 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 | 173,417,705 | |
| -1 | -173,417,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,417,705.
Example:
1 x 173,417,705 = 173,417,705
and
-1 x -173,417,705 = 173,417,705
Notice both answers equal 173,417,705
With that explanation out of the way, let's continue. Next, we take the number 173,417,705 and divide it by 2:
173,417,705 ÷ 2 = 86,708,852.5
If the quotient is a whole number, then 2 and 86,708,852.5 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 | 173,417,705 | |
| -1 | -173,417,705 |
Now, we try dividing 173,417,705 by 3:
173,417,705 ÷ 3 = 57,805,901.6667
If the quotient is a whole number, then 3 and 57,805,901.6667 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 | 173,417,705 | |
| -1 | -173,417,705 |
Let's try dividing by 4:
173,417,705 ÷ 4 = 43,354,426.25
If the quotient is a whole number, then 4 and 43,354,426.25 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 | 173,417,705 | |
| -1 | 173,417,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 73 | 185 | 365 | 2,701 | 12,841 | 13,505 | 64,205 | 475,117 | 937,393 | 2,375,585 | 4,686,965 | 34,683,541 | 173,417,705 |
| -1 | -5 | -37 | -73 | -185 | -365 | -2,701 | -12,841 | -13,505 | -64,205 | -475,117 | -937,393 | -2,375,585 | -4,686,965 | -34,683,541 | -173,417,705 |
