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 6,187,313, 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 | 6,187,313 | |
| -1 | -6,187,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,187,313.
Example:
1 x 6,187,313 = 6,187,313
and
-1 x -6,187,313 = 6,187,313
Notice both answers equal 6,187,313
With that explanation out of the way, let's continue. Next, we take the number 6,187,313 and divide it by 2:
6,187,313 ÷ 2 = 3,093,656.5
If the quotient is a whole number, then 2 and 3,093,656.5 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 | 6,187,313 | |
| -1 | -6,187,313 |
Now, we try dividing 6,187,313 by 3:
6,187,313 ÷ 3 = 2,062,437.6667
If the quotient is a whole number, then 3 and 2,062,437.6667 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 | 6,187,313 | |
| -1 | -6,187,313 |
Let's try dividing by 4:
6,187,313 ÷ 4 = 1,546,828.25
If the quotient is a whole number, then 4 and 1,546,828.25 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 | 6,187,313 | |
| -1 | 6,187,313 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 103 | 127 | 473 | 1,133 | 1,397 | 4,429 | 5,461 | 13,081 | 48,719 | 60,071 | 143,891 | 562,483 | 6,187,313 |
| -1 | -11 | -43 | -103 | -127 | -473 | -1,133 | -1,397 | -4,429 | -5,461 | -13,081 | -48,719 | -60,071 | -143,891 | -562,483 | -6,187,313 |
