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 8,306,545, 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 | 8,306,545 | |
| -1 | -8,306,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,306,545.
Example:
1 x 8,306,545 = 8,306,545
and
-1 x -8,306,545 = 8,306,545
Notice both answers equal 8,306,545
With that explanation out of the way, let's continue. Next, we take the number 8,306,545 and divide it by 2:
8,306,545 ÷ 2 = 4,153,272.5
If the quotient is a whole number, then 2 and 4,153,272.5 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 | 8,306,545 | |
| -1 | -8,306,545 |
Now, we try dividing 8,306,545 by 3:
8,306,545 ÷ 3 = 2,768,848.3333
If the quotient is a whole number, then 3 and 2,768,848.3333 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 | 8,306,545 | |
| -1 | -8,306,545 |
Let's try dividing by 4:
8,306,545 ÷ 4 = 2,076,636.25
If the quotient is a whole number, then 4 and 2,076,636.25 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 | 8,306,545 | |
| -1 | 8,306,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 611 | 2,719 | 3,055 | 13,595 | 35,347 | 127,793 | 176,735 | 638,965 | 1,661,309 | 8,306,545 |
| -1 | -5 | -13 | -47 | -65 | -235 | -611 | -2,719 | -3,055 | -13,595 | -35,347 | -127,793 | -176,735 | -638,965 | -1,661,309 | -8,306,545 |
