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 13,304,213, 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 | 13,304,213 | |
| -1 | -13,304,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,304,213.
Example:
1 x 13,304,213 = 13,304,213
and
-1 x -13,304,213 = 13,304,213
Notice both answers equal 13,304,213
With that explanation out of the way, let's continue. Next, we take the number 13,304,213 and divide it by 2:
13,304,213 ÷ 2 = 6,652,106.5
If the quotient is a whole number, then 2 and 6,652,106.5 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 | 13,304,213 | |
| -1 | -13,304,213 |
Now, we try dividing 13,304,213 by 3:
13,304,213 ÷ 3 = 4,434,737.6667
If the quotient is a whole number, then 3 and 4,434,737.6667 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 | 13,304,213 | |
| -1 | -13,304,213 |
Let's try dividing by 4:
13,304,213 ÷ 4 = 3,326,053.25
If the quotient is a whole number, then 4 and 3,326,053.25 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 | 13,304,213 | |
| -1 | 13,304,213 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 109 | 229 | 533 | 1,417 | 2,977 | 4,469 | 9,389 | 24,961 | 58,097 | 122,057 | 324,493 | 1,023,401 | 13,304,213 |
| -1 | -13 | -41 | -109 | -229 | -533 | -1,417 | -2,977 | -4,469 | -9,389 | -24,961 | -58,097 | -122,057 | -324,493 | -1,023,401 | -13,304,213 |
