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 4,081,345, 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 | 4,081,345 | |
| -1 | -4,081,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,081,345.
Example:
1 x 4,081,345 = 4,081,345
and
-1 x -4,081,345 = 4,081,345
Notice both answers equal 4,081,345
With that explanation out of the way, let's continue. Next, we take the number 4,081,345 and divide it by 2:
4,081,345 ÷ 2 = 2,040,672.5
If the quotient is a whole number, then 2 and 2,040,672.5 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 | 4,081,345 | |
| -1 | -4,081,345 |
Now, we try dividing 4,081,345 by 3:
4,081,345 ÷ 3 = 1,360,448.3333
If the quotient is a whole number, then 3 and 1,360,448.3333 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 | 4,081,345 | |
| -1 | -4,081,345 |
Let's try dividing by 4:
4,081,345 ÷ 4 = 1,020,336.25
If the quotient is a whole number, then 4 and 1,020,336.25 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 | 4,081,345 | |
| -1 | 4,081,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 43 | 205 | 215 | 463 | 1,763 | 2,315 | 8,815 | 18,983 | 19,909 | 94,915 | 99,545 | 816,269 | 4,081,345 |
| -1 | -5 | -41 | -43 | -205 | -215 | -463 | -1,763 | -2,315 | -8,815 | -18,983 | -19,909 | -94,915 | -99,545 | -816,269 | -4,081,345 |
