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 13,320,307, 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 | 13,320,307 | |
| -1 | -13,320,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,320,307.
Example:
1 x 13,320,307 = 13,320,307
and
-1 x -13,320,307 = 13,320,307
Notice both answers equal 13,320,307
With that explanation out of the way, let's continue. Next, we take the number 13,320,307 and divide it by 2:
13,320,307 ÷ 2 = 6,660,153.5
If the quotient is a whole number, then 2 and 6,660,153.5 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 | 13,320,307 | |
| -1 | -13,320,307 |
Now, we try dividing 13,320,307 by 3:
13,320,307 ÷ 3 = 4,440,102.3333
If the quotient is a whole number, then 3 and 4,440,102.3333 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 | 13,320,307 | |
| -1 | -13,320,307 |
Let's try dividing by 4:
13,320,307 ÷ 4 = 3,330,076.75
If the quotient is a whole number, then 4 and 3,330,076.75 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 | 13,320,307 | |
| -1 | 13,320,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 1,001 | 1,901 | 7,007 | 13,307 | 20,911 | 24,713 | 93,149 | 146,377 | 172,991 | 271,843 | 1,024,639 | 1,210,937 | 1,902,901 | 13,320,307 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -1,001 | -1,901 | -7,007 | -13,307 | -20,911 | -24,713 | -93,149 | -146,377 | -172,991 | -271,843 | -1,024,639 | -1,210,937 | -1,902,901 | -13,320,307 |
