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 13,346,443, 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 | 13,346,443 | |
| -1 | -13,346,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,346,443.
Example:
1 x 13,346,443 = 13,346,443
and
-1 x -13,346,443 = 13,346,443
Notice both answers equal 13,346,443
With that explanation out of the way, let's continue. Next, we take the number 13,346,443 and divide it by 2:
13,346,443 ÷ 2 = 6,673,221.5
If the quotient is a whole number, then 2 and 6,673,221.5 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 | 13,346,443 | |
| -1 | -13,346,443 |
Now, we try dividing 13,346,443 by 3:
13,346,443 ÷ 3 = 4,448,814.3333
If the quotient is a whole number, then 3 and 4,448,814.3333 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 | 13,346,443 | |
| -1 | -13,346,443 |
Let's try dividing by 4:
13,346,443 ÷ 4 = 3,336,610.75
If the quotient is a whole number, then 4 and 3,336,610.75 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 | 13,346,443 | |
| -1 | 13,346,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 101 | 293 | 451 | 1,111 | 3,223 | 4,141 | 12,013 | 29,593 | 45,551 | 132,143 | 325,523 | 1,213,313 | 13,346,443 |
| -1 | -11 | -41 | -101 | -293 | -451 | -1,111 | -3,223 | -4,141 | -12,013 | -29,593 | -45,551 | -132,143 | -325,523 | -1,213,313 | -13,346,443 |
