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 13,343,317, 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 | 13,343,317 | |
| -1 | -13,343,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,343,317.
Example:
1 x 13,343,317 = 13,343,317
and
-1 x -13,343,317 = 13,343,317
Notice both answers equal 13,343,317
With that explanation out of the way, let's continue. Next, we take the number 13,343,317 and divide it by 2:
13,343,317 ÷ 2 = 6,671,658.5
If the quotient is a whole number, then 2 and 6,671,658.5 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 | 13,343,317 | |
| -1 | -13,343,317 |
Now, we try dividing 13,343,317 by 3:
13,343,317 ÷ 3 = 4,447,772.3333
If the quotient is a whole number, then 3 and 4,447,772.3333 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 | 13,343,317 | |
| -1 | -13,343,317 |
Let's try dividing by 4:
13,343,317 ÷ 4 = 3,335,829.25
If the quotient is a whole number, then 4 and 3,335,829.25 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 | 13,343,317 | |
| -1 | 13,343,317 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 173 | 221 | 349 | 2,249 | 2,941 | 4,537 | 5,933 | 38,233 | 60,377 | 77,129 | 784,901 | 1,026,409 | 13,343,317 |
| -1 | -13 | -17 | -173 | -221 | -349 | -2,249 | -2,941 | -4,537 | -5,933 | -38,233 | -60,377 | -77,129 | -784,901 | -1,026,409 | -13,343,317 |
