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 13,289,297, 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 | 13,289,297 | |
| -1 | -13,289,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,289,297.
Example:
1 x 13,289,297 = 13,289,297
and
-1 x -13,289,297 = 13,289,297
Notice both answers equal 13,289,297
With that explanation out of the way, let's continue. Next, we take the number 13,289,297 and divide it by 2:
13,289,297 ÷ 2 = 6,644,648.5
If the quotient is a whole number, then 2 and 6,644,648.5 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 | 13,289,297 | |
| -1 | -13,289,297 |
Now, we try dividing 13,289,297 by 3:
13,289,297 ÷ 3 = 4,429,765.6667
If the quotient is a whole number, then 3 and 4,429,765.6667 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 | 13,289,297 | |
| -1 | -13,289,297 |
Let's try dividing by 4:
13,289,297 ÷ 4 = 3,322,324.25
If the quotient is a whole number, then 4 and 3,322,324.25 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 | 13,289,297 | |
| -1 | 13,289,297 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 47 | 217 | 329 | 1,303 | 1,457 | 9,121 | 10,199 | 40,393 | 61,241 | 282,751 | 428,687 | 1,898,471 | 13,289,297 |
| -1 | -7 | -31 | -47 | -217 | -329 | -1,303 | -1,457 | -9,121 | -10,199 | -40,393 | -61,241 | -282,751 | -428,687 | -1,898,471 | -13,289,297 |
