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 13,256,441, 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 | 13,256,441 | |
| -1 | -13,256,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,256,441.
Example:
1 x 13,256,441 = 13,256,441
and
-1 x -13,256,441 = 13,256,441
Notice both answers equal 13,256,441
With that explanation out of the way, let's continue. Next, we take the number 13,256,441 and divide it by 2:
13,256,441 ÷ 2 = 6,628,220.5
If the quotient is a whole number, then 2 and 6,628,220.5 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 | 13,256,441 | |
| -1 | -13,256,441 |
Now, we try dividing 13,256,441 by 3:
13,256,441 ÷ 3 = 4,418,813.6667
If the quotient is a whole number, then 3 and 4,418,813.6667 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 | 13,256,441 | |
| -1 | -13,256,441 |
Let's try dividing by 4:
13,256,441 ÷ 4 = 3,314,110.25
If the quotient is a whole number, then 4 and 3,314,110.25 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 | 13,256,441 | |
| -1 | 13,256,441 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 151 | 253 | 347 | 1,661 | 3,473 | 3,817 | 7,981 | 38,203 | 52,397 | 87,791 | 576,367 | 1,205,131 | 13,256,441 |
| -1 | -11 | -23 | -151 | -253 | -347 | -1,661 | -3,473 | -3,817 | -7,981 | -38,203 | -52,397 | -87,791 | -576,367 | -1,205,131 | -13,256,441 |
