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 8,270,561, 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 | 8,270,561 | |
| -1 | -8,270,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,270,561.
Example:
1 x 8,270,561 = 8,270,561
and
-1 x -8,270,561 = 8,270,561
Notice both answers equal 8,270,561
With that explanation out of the way, let's continue. Next, we take the number 8,270,561 and divide it by 2:
8,270,561 ÷ 2 = 4,135,280.5
If the quotient is a whole number, then 2 and 4,135,280.5 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 | 8,270,561 | |
| -1 | -8,270,561 |
Now, we try dividing 8,270,561 by 3:
8,270,561 ÷ 3 = 2,756,853.6667
If the quotient is a whole number, then 3 and 2,756,853.6667 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 | 8,270,561 | |
| -1 | -8,270,561 |
Let's try dividing by 4:
8,270,561 ÷ 4 = 2,067,640.25
If the quotient is a whole number, then 4 and 2,067,640.25 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 | 8,270,561 | |
| -1 | 8,270,561 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 59 | 263 | 533 | 767 | 2,419 | 3,419 | 10,783 | 15,517 | 31,447 | 140,179 | 201,721 | 636,197 | 8,270,561 |
| -1 | -13 | -41 | -59 | -263 | -533 | -767 | -2,419 | -3,419 | -10,783 | -15,517 | -31,447 | -140,179 | -201,721 | -636,197 | -8,270,561 |
