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 13,320,203, 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 | 13,320,203 | |
| -1 | -13,320,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,320,203.
Example:
1 x 13,320,203 = 13,320,203
and
-1 x -13,320,203 = 13,320,203
Notice both answers equal 13,320,203
With that explanation out of the way, let's continue. Next, we take the number 13,320,203 and divide it by 2:
13,320,203 ÷ 2 = 6,660,101.5
If the quotient is a whole number, then 2 and 6,660,101.5 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 | 13,320,203 | |
| -1 | -13,320,203 |
Now, we try dividing 13,320,203 by 3:
13,320,203 ÷ 3 = 4,440,067.6667
If the quotient is a whole number, then 3 and 4,440,067.6667 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 | 13,320,203 | |
| -1 | -13,320,203 |
Let's try dividing by 4:
13,320,203 ÷ 4 = 3,330,050.75
If the quotient is a whole number, then 4 and 3,330,050.75 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 | 13,320,203 | |
| -1 | 13,320,203 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 67 | 373 | 533 | 871 | 2,747 | 4,849 | 15,293 | 24,991 | 35,711 | 198,809 | 324,883 | 1,024,631 | 13,320,203 |
| -1 | -13 | -41 | -67 | -373 | -533 | -871 | -2,747 | -4,849 | -15,293 | -24,991 | -35,711 | -198,809 | -324,883 | -1,024,631 | -13,320,203 |
