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 8,594,905, 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 | 8,594,905 | |
| -1 | -8,594,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,594,905.
Example:
1 x 8,594,905 = 8,594,905
and
-1 x -8,594,905 = 8,594,905
Notice both answers equal 8,594,905
With that explanation out of the way, let's continue. Next, we take the number 8,594,905 and divide it by 2:
8,594,905 ÷ 2 = 4,297,452.5
If the quotient is a whole number, then 2 and 4,297,452.5 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 | 8,594,905 | |
| -1 | -8,594,905 |
Now, we try dividing 8,594,905 by 3:
8,594,905 ÷ 3 = 2,864,968.3333
If the quotient is a whole number, then 3 and 2,864,968.3333 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 | 8,594,905 | |
| -1 | -8,594,905 |
Let's try dividing by 4:
8,594,905 ÷ 4 = 2,148,726.25
If the quotient is a whole number, then 4 and 2,148,726.25 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 | 8,594,905 | |
| -1 | 8,594,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 71 | 155 | 341 | 355 | 781 | 1,705 | 2,201 | 3,905 | 5,041 | 11,005 | 24,211 | 25,205 | 55,451 | 121,055 | 156,271 | 277,255 | 781,355 | 1,718,981 | 8,594,905 |
| -1 | -5 | -11 | -31 | -55 | -71 | -155 | -341 | -355 | -781 | -1,705 | -2,201 | -3,905 | -5,041 | -11,005 | -24,211 | -25,205 | -55,451 | -121,055 | -156,271 | -277,255 | -781,355 | -1,718,981 | -8,594,905 |
