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 8,440,565, 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 | 8,440,565 | |
| -1 | -8,440,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,440,565.
Example:
1 x 8,440,565 = 8,440,565
and
-1 x -8,440,565 = 8,440,565
Notice both answers equal 8,440,565
With that explanation out of the way, let's continue. Next, we take the number 8,440,565 and divide it by 2:
8,440,565 ÷ 2 = 4,220,282.5
If the quotient is a whole number, then 2 and 4,220,282.5 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 | 8,440,565 | |
| -1 | -8,440,565 |
Now, we try dividing 8,440,565 by 3:
8,440,565 ÷ 3 = 2,813,521.6667
If the quotient is a whole number, then 3 and 2,813,521.6667 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 | 8,440,565 | |
| -1 | -8,440,565 |
Let's try dividing by 4:
8,440,565 ÷ 4 = 2,110,141.25
If the quotient is a whole number, then 4 and 2,110,141.25 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 | 8,440,565 | |
| -1 | 8,440,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 349 | 691 | 1,745 | 2,443 | 3,455 | 4,837 | 12,215 | 24,185 | 241,159 | 1,205,795 | 1,688,113 | 8,440,565 |
| -1 | -5 | -7 | -35 | -349 | -691 | -1,745 | -2,443 | -3,455 | -4,837 | -12,215 | -24,185 | -241,159 | -1,205,795 | -1,688,113 | -8,440,565 |
