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 171,360,013, 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 | 171,360,013 | |
| -1 | -171,360,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,360,013.
Example:
1 x 171,360,013 = 171,360,013
and
-1 x -171,360,013 = 171,360,013
Notice both answers equal 171,360,013
With that explanation out of the way, let's continue. Next, we take the number 171,360,013 and divide it by 2:
171,360,013 ÷ 2 = 85,680,006.5
If the quotient is a whole number, then 2 and 85,680,006.5 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 | 171,360,013 | |
| -1 | -171,360,013 |
Now, we try dividing 171,360,013 by 3:
171,360,013 ÷ 3 = 57,120,004.3333
If the quotient is a whole number, then 3 and 57,120,004.3333 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 | 171,360,013 | |
| -1 | -171,360,013 |
Let's try dividing by 4:
171,360,013 ÷ 4 = 42,840,003.25
If the quotient is a whole number, then 4 and 42,840,003.25 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 | 171,360,013 | |
| -1 | 171,360,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 229 | 649 | 1,153 | 2,519 | 12,683 | 13,511 | 68,027 | 148,621 | 264,037 | 748,297 | 2,904,407 | 15,578,183 | 171,360,013 |
| -1 | -11 | -59 | -229 | -649 | -1,153 | -2,519 | -12,683 | -13,511 | -68,027 | -148,621 | -264,037 | -748,297 | -2,904,407 | -15,578,183 | -171,360,013 |
