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 6,613,187, 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 | 6,613,187 | |
| -1 | -6,613,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,613,187.
Example:
1 x 6,613,187 = 6,613,187
and
-1 x -6,613,187 = 6,613,187
Notice both answers equal 6,613,187
With that explanation out of the way, let's continue. Next, we take the number 6,613,187 and divide it by 2:
6,613,187 ÷ 2 = 3,306,593.5
If the quotient is a whole number, then 2 and 3,306,593.5 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 | 6,613,187 | |
| -1 | -6,613,187 |
Now, we try dividing 6,613,187 by 3:
6,613,187 ÷ 3 = 2,204,395.6667
If the quotient is a whole number, then 3 and 2,204,395.6667 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 | 6,613,187 | |
| -1 | -6,613,187 |
Let's try dividing by 4:
6,613,187 ÷ 4 = 1,653,296.75
If the quotient is a whole number, then 4 and 1,653,296.75 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 | 6,613,187 | |
| -1 | 6,613,187 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 289 | 467 | 833 | 2,023 | 3,269 | 7,939 | 14,161 | 22,883 | 55,573 | 134,963 | 389,011 | 944,741 | 6,613,187 |
| -1 | -7 | -17 | -49 | -119 | -289 | -467 | -833 | -2,023 | -3,269 | -7,939 | -14,161 | -22,883 | -55,573 | -134,963 | -389,011 | -944,741 | -6,613,187 |
