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 6,561,709, 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 | 6,561,709 | |
| -1 | -6,561,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,561,709.
Example:
1 x 6,561,709 = 6,561,709
and
-1 x -6,561,709 = 6,561,709
Notice both answers equal 6,561,709
With that explanation out of the way, let's continue. Next, we take the number 6,561,709 and divide it by 2:
6,561,709 ÷ 2 = 3,280,854.5
If the quotient is a whole number, then 2 and 3,280,854.5 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 | 6,561,709 | |
| -1 | -6,561,709 |
Now, we try dividing 6,561,709 by 3:
6,561,709 ÷ 3 = 2,187,236.3333
If the quotient is a whole number, then 3 and 2,187,236.3333 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 | 6,561,709 | |
| -1 | -6,561,709 |
Let's try dividing by 4:
6,561,709 ÷ 4 = 1,640,427.25
If the quotient is a whole number, then 4 and 1,640,427.25 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 | 6,561,709 | |
| -1 | 6,561,709 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 61 | 77 | 121 | 127 | 427 | 671 | 847 | 889 | 1,397 | 4,697 | 7,381 | 7,747 | 9,779 | 15,367 | 51,667 | 54,229 | 85,217 | 107,569 | 596,519 | 937,387 | 6,561,709 |
| -1 | -7 | -11 | -61 | -77 | -121 | -127 | -427 | -671 | -847 | -889 | -1,397 | -4,697 | -7,381 | -7,747 | -9,779 | -15,367 | -51,667 | -54,229 | -85,217 | -107,569 | -596,519 | -937,387 | -6,561,709 |
