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 13,234,013, 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 | 13,234,013 | |
| -1 | -13,234,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,234,013.
Example:
1 x 13,234,013 = 13,234,013
and
-1 x -13,234,013 = 13,234,013
Notice both answers equal 13,234,013
With that explanation out of the way, let's continue. Next, we take the number 13,234,013 and divide it by 2:
13,234,013 ÷ 2 = 6,617,006.5
If the quotient is a whole number, then 2 and 6,617,006.5 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 | 13,234,013 | |
| -1 | -13,234,013 |
Now, we try dividing 13,234,013 by 3:
13,234,013 ÷ 3 = 4,411,337.6667
If the quotient is a whole number, then 3 and 4,411,337.6667 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 | 13,234,013 | |
| -1 | -13,234,013 |
Let's try dividing by 4:
13,234,013 ÷ 4 = 3,308,503.25
If the quotient is a whole number, then 4 and 3,308,503.25 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 | 13,234,013 | |
| -1 | 13,234,013 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 131 | 247 | 409 | 1,703 | 2,489 | 5,317 | 7,771 | 32,357 | 53,579 | 101,023 | 696,527 | 1,018,001 | 13,234,013 |
| -1 | -13 | -19 | -131 | -247 | -409 | -1,703 | -2,489 | -5,317 | -7,771 | -32,357 | -53,579 | -101,023 | -696,527 | -1,018,001 | -13,234,013 |
