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 4,044,215, 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 | 4,044,215 | |
| -1 | -4,044,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,044,215.
Example:
1 x 4,044,215 = 4,044,215
and
-1 x -4,044,215 = 4,044,215
Notice both answers equal 4,044,215
With that explanation out of the way, let's continue. Next, we take the number 4,044,215 and divide it by 2:
4,044,215 ÷ 2 = 2,022,107.5
If the quotient is a whole number, then 2 and 2,022,107.5 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 | 4,044,215 | |
| -1 | -4,044,215 |
Now, we try dividing 4,044,215 by 3:
4,044,215 ÷ 3 = 1,348,071.6667
If the quotient is a whole number, then 3 and 1,348,071.6667 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 | 4,044,215 | |
| -1 | -4,044,215 |
Let's try dividing by 4:
4,044,215 ÷ 4 = 1,011,053.75
If the quotient is a whole number, then 4 and 1,011,053.75 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 | 4,044,215 | |
| -1 | 4,044,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 971 | 4,165 | 4,855 | 6,797 | 16,507 | 33,985 | 47,579 | 82,535 | 115,549 | 237,895 | 577,745 | 808,843 | 4,044,215 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -971 | -4,165 | -4,855 | -6,797 | -16,507 | -33,985 | -47,579 | -82,535 | -115,549 | -237,895 | -577,745 | -808,843 | -4,044,215 |
