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 13,256,545, 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 | 13,256,545 | |
| -1 | -13,256,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,256,545.
Example:
1 x 13,256,545 = 13,256,545
and
-1 x -13,256,545 = 13,256,545
Notice both answers equal 13,256,545
With that explanation out of the way, let's continue. Next, we take the number 13,256,545 and divide it by 2:
13,256,545 ÷ 2 = 6,628,272.5
If the quotient is a whole number, then 2 and 6,628,272.5 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 | 13,256,545 | |
| -1 | -13,256,545 |
Now, we try dividing 13,256,545 by 3:
13,256,545 ÷ 3 = 4,418,848.3333
If the quotient is a whole number, then 3 and 4,418,848.3333 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 | 13,256,545 | |
| -1 | -13,256,545 |
Let's try dividing by 4:
13,256,545 ÷ 4 = 3,314,136.25
If the quotient is a whole number, then 4 and 3,314,136.25 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 | 13,256,545 | |
| -1 | 13,256,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 131 | 185 | 547 | 655 | 2,735 | 4,847 | 20,239 | 24,235 | 71,657 | 101,195 | 358,285 | 2,651,309 | 13,256,545 |
| -1 | -5 | -37 | -131 | -185 | -547 | -655 | -2,735 | -4,847 | -20,239 | -24,235 | -71,657 | -101,195 | -358,285 | -2,651,309 | -13,256,545 |
