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 4,055,345, 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 | 4,055,345 | |
| -1 | -4,055,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,055,345.
Example:
1 x 4,055,345 = 4,055,345
and
-1 x -4,055,345 = 4,055,345
Notice both answers equal 4,055,345
With that explanation out of the way, let's continue. Next, we take the number 4,055,345 and divide it by 2:
4,055,345 ÷ 2 = 2,027,672.5
If the quotient is a whole number, then 2 and 2,027,672.5 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 | 4,055,345 | |
| -1 | -4,055,345 |
Now, we try dividing 4,055,345 by 3:
4,055,345 ÷ 3 = 1,351,781.6667
If the quotient is a whole number, then 3 and 1,351,781.6667 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 | 4,055,345 | |
| -1 | -4,055,345 |
Let's try dividing by 4:
4,055,345 ÷ 4 = 1,013,836.25
If the quotient is a whole number, then 4 and 1,013,836.25 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 | 4,055,345 | |
| -1 | 4,055,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 109 | 545 | 763 | 1,063 | 3,815 | 5,315 | 7,441 | 37,205 | 115,867 | 579,335 | 811,069 | 4,055,345 |
| -1 | -5 | -7 | -35 | -109 | -545 | -763 | -1,063 | -3,815 | -5,315 | -7,441 | -37,205 | -115,867 | -579,335 | -811,069 | -4,055,345 |
