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 7,208,443, 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 | 7,208,443 | |
| -1 | -7,208,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,208,443.
Example:
1 x 7,208,443 = 7,208,443
and
-1 x -7,208,443 = 7,208,443
Notice both answers equal 7,208,443
With that explanation out of the way, let's continue. Next, we take the number 7,208,443 and divide it by 2:
7,208,443 ÷ 2 = 3,604,221.5
If the quotient is a whole number, then 2 and 3,604,221.5 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 | 7,208,443 | |
| -1 | -7,208,443 |
Now, we try dividing 7,208,443 by 3:
7,208,443 ÷ 3 = 2,402,814.3333
If the quotient is a whole number, then 3 and 2,402,814.3333 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 | 7,208,443 | |
| -1 | -7,208,443 |
Let's try dividing by 4:
7,208,443 ÷ 4 = 1,802,110.75
If the quotient is a whole number, then 4 and 1,802,110.75 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 | 7,208,443 | |
| -1 | 7,208,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 59 | 319 | 383 | 649 | 1,711 | 4,213 | 11,107 | 18,821 | 22,597 | 122,177 | 248,567 | 655,313 | 7,208,443 |
| -1 | -11 | -29 | -59 | -319 | -383 | -649 | -1,711 | -4,213 | -11,107 | -18,821 | -22,597 | -122,177 | -248,567 | -655,313 | -7,208,443 |
