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 6,160,231, 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 | 6,160,231 | |
| -1 | -6,160,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,160,231.
Example:
1 x 6,160,231 = 6,160,231
and
-1 x -6,160,231 = 6,160,231
Notice both answers equal 6,160,231
With that explanation out of the way, let's continue. Next, we take the number 6,160,231 and divide it by 2:
6,160,231 ÷ 2 = 3,080,115.5
If the quotient is a whole number, then 2 and 3,080,115.5 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 | 6,160,231 | |
| -1 | -6,160,231 |
Now, we try dividing 6,160,231 by 3:
6,160,231 ÷ 3 = 2,053,410.3333
If the quotient is a whole number, then 3 and 2,053,410.3333 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 | 6,160,231 | |
| -1 | -6,160,231 |
Let's try dividing by 4:
6,160,231 ÷ 4 = 1,540,057.75
If the quotient is a whole number, then 4 and 1,540,057.75 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 | 6,160,231 | |
| -1 | 6,160,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 539 | 847 | 1,039 | 5,929 | 7,273 | 11,429 | 50,911 | 80,003 | 125,719 | 560,021 | 880,033 | 6,160,231 |
| -1 | -7 | -11 | -49 | -77 | -121 | -539 | -847 | -1,039 | -5,929 | -7,273 | -11,429 | -50,911 | -80,003 | -125,719 | -560,021 | -880,033 | -6,160,231 |
