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 15,832,117, 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 | 15,832,117 | |
| -1 | -15,832,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,832,117.
Example:
1 x 15,832,117 = 15,832,117
and
-1 x -15,832,117 = 15,832,117
Notice both answers equal 15,832,117
With that explanation out of the way, let's continue. Next, we take the number 15,832,117 and divide it by 2:
15,832,117 ÷ 2 = 7,916,058.5
If the quotient is a whole number, then 2 and 7,916,058.5 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 | 15,832,117 | |
| -1 | -15,832,117 |
Now, we try dividing 15,832,117 by 3:
15,832,117 ÷ 3 = 5,277,372.3333
If the quotient is a whole number, then 3 and 5,277,372.3333 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 | 15,832,117 | |
| -1 | -15,832,117 |
Let's try dividing by 4:
15,832,117 ÷ 4 = 3,958,029.25
If the quotient is a whole number, then 4 and 3,958,029.25 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 | 15,832,117 | |
| -1 | 15,832,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 233 | 571 | 1,631 | 3,961 | 3,997 | 9,707 | 27,727 | 67,949 | 133,043 | 931,301 | 2,261,731 | 15,832,117 |
| -1 | -7 | -17 | -119 | -233 | -571 | -1,631 | -3,961 | -3,997 | -9,707 | -27,727 | -67,949 | -133,043 | -931,301 | -2,261,731 | -15,832,117 |
