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 171,823,301, 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 | 171,823,301 | |
| -1 | -171,823,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,823,301.
Example:
1 x 171,823,301 = 171,823,301
and
-1 x -171,823,301 = 171,823,301
Notice both answers equal 171,823,301
With that explanation out of the way, let's continue. Next, we take the number 171,823,301 and divide it by 2:
171,823,301 ÷ 2 = 85,911,650.5
If the quotient is a whole number, then 2 and 85,911,650.5 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 | 171,823,301 | |
| -1 | -171,823,301 |
Now, we try dividing 171,823,301 by 3:
171,823,301 ÷ 3 = 57,274,433.6667
If the quotient is a whole number, then 3 and 57,274,433.6667 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 | 171,823,301 | |
| -1 | -171,823,301 |
Let's try dividing by 4:
171,823,301 ÷ 4 = 42,955,825.25
If the quotient is a whole number, then 4 and 42,955,825.25 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 | 171,823,301 | |
| -1 | 171,823,301 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 37 | 221 | 481 | 629 | 8,177 | 21,013 | 273,169 | 357,221 | 777,481 | 4,643,873 | 10,107,253 | 13,217,177 | 171,823,301 |
| -1 | -13 | -17 | -37 | -221 | -481 | -629 | -8,177 | -21,013 | -273,169 | -357,221 | -777,481 | -4,643,873 | -10,107,253 | -13,217,177 | -171,823,301 |
