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 3,086,369, 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 | 3,086,369 | |
| -1 | -3,086,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,086,369.
Example:
1 x 3,086,369 = 3,086,369
and
-1 x -3,086,369 = 3,086,369
Notice both answers equal 3,086,369
With that explanation out of the way, let's continue. Next, we take the number 3,086,369 and divide it by 2:
3,086,369 ÷ 2 = 1,543,184.5
If the quotient is a whole number, then 2 and 1,543,184.5 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 | 3,086,369 | |
| -1 | -3,086,369 |
Now, we try dividing 3,086,369 by 3:
3,086,369 ÷ 3 = 1,028,789.6667
If the quotient is a whole number, then 3 and 1,028,789.6667 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 | 3,086,369 | |
| -1 | -3,086,369 |
Let's try dividing by 4:
3,086,369 ÷ 4 = 771,592.25
If the quotient is a whole number, then 4 and 771,592.25 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 | 3,086,369 | |
| -1 | 3,086,369 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 113 | 143 | 191 | 1,243 | 1,469 | 2,101 | 2,483 | 16,159 | 21,583 | 27,313 | 237,413 | 280,579 | 3,086,369 |
| -1 | -11 | -13 | -113 | -143 | -191 | -1,243 | -1,469 | -2,101 | -2,483 | -16,159 | -21,583 | -27,313 | -237,413 | -280,579 | -3,086,369 |
