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 8,094,905, 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 | 8,094,905 | |
| -1 | -8,094,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,094,905.
Example:
1 x 8,094,905 = 8,094,905
and
-1 x -8,094,905 = 8,094,905
Notice both answers equal 8,094,905
With that explanation out of the way, let's continue. Next, we take the number 8,094,905 and divide it by 2:
8,094,905 ÷ 2 = 4,047,452.5
If the quotient is a whole number, then 2 and 4,047,452.5 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 | 8,094,905 | |
| -1 | -8,094,905 |
Now, we try dividing 8,094,905 by 3:
8,094,905 ÷ 3 = 2,698,301.6667
If the quotient is a whole number, then 3 and 2,698,301.6667 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 | 8,094,905 | |
| -1 | -8,094,905 |
Let's try dividing by 4:
8,094,905 ÷ 4 = 2,023,726.25
If the quotient is a whole number, then 4 and 2,023,726.25 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 | 8,094,905 | |
| -1 | 8,094,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 17,791 | 88,955 | 124,537 | 231,283 | 622,685 | 1,156,415 | 1,618,981 | 8,094,905 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -17,791 | -88,955 | -124,537 | -231,283 | -622,685 | -1,156,415 | -1,618,981 | -8,094,905 |
