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 13,950,443, 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 | 13,950,443 | |
| -1 | -13,950,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,950,443.
Example:
1 x 13,950,443 = 13,950,443
and
-1 x -13,950,443 = 13,950,443
Notice both answers equal 13,950,443
With that explanation out of the way, let's continue. Next, we take the number 13,950,443 and divide it by 2:
13,950,443 ÷ 2 = 6,975,221.5
If the quotient is a whole number, then 2 and 6,975,221.5 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 | 13,950,443 | |
| -1 | -13,950,443 |
Now, we try dividing 13,950,443 by 3:
13,950,443 ÷ 3 = 4,650,147.6667
If the quotient is a whole number, then 3 and 4,650,147.6667 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 | 13,950,443 | |
| -1 | -13,950,443 |
Let's try dividing by 4:
13,950,443 ÷ 4 = 3,487,610.75
If the quotient is a whole number, then 4 and 3,487,610.75 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 | 13,950,443 | |
| -1 | 13,950,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 37 | 97 | 169 | 299 | 481 | 851 | 1,261 | 2,231 | 3,589 | 3,887 | 6,253 | 11,063 | 16,393 | 29,003 | 46,657 | 82,547 | 143,819 | 377,039 | 606,541 | 1,073,111 | 13,950,443 |
| -1 | -13 | -23 | -37 | -97 | -169 | -299 | -481 | -851 | -1,261 | -2,231 | -3,589 | -3,887 | -6,253 | -11,063 | -16,393 | -29,003 | -46,657 | -82,547 | -143,819 | -377,039 | -606,541 | -1,073,111 | -13,950,443 |
