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 171,010,727, 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 | 171,010,727 | |
| -1 | -171,010,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,010,727.
Example:
1 x 171,010,727 = 171,010,727
and
-1 x -171,010,727 = 171,010,727
Notice both answers equal 171,010,727
With that explanation out of the way, let's continue. Next, we take the number 171,010,727 and divide it by 2:
171,010,727 ÷ 2 = 85,505,363.5
If the quotient is a whole number, then 2 and 85,505,363.5 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 | 171,010,727 | |
| -1 | -171,010,727 |
Now, we try dividing 171,010,727 by 3:
171,010,727 ÷ 3 = 57,003,575.6667
If the quotient is a whole number, then 3 and 57,003,575.6667 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 | 171,010,727 | |
| -1 | -171,010,727 |
Let's try dividing by 4:
171,010,727 ÷ 4 = 42,752,681.75
If the quotient is a whole number, then 4 and 42,752,681.75 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 | 171,010,727 | |
| -1 | 171,010,727 |
If you did it right, you will end up with this table:
| 1 | 23 | 139 | 149 | 359 | 3,197 | 3,427 | 8,257 | 20,711 | 49,901 | 53,491 | 476,353 | 1,147,723 | 1,230,293 | 7,435,249 | 171,010,727 |
| -1 | -23 | -139 | -149 | -359 | -3,197 | -3,427 | -8,257 | -20,711 | -49,901 | -53,491 | -476,353 | -1,147,723 | -1,230,293 | -7,435,249 | -171,010,727 |
