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 13,404,655, 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 | 13,404,655 | |
| -1 | -13,404,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,404,655.
Example:
1 x 13,404,655 = 13,404,655
and
-1 x -13,404,655 = 13,404,655
Notice both answers equal 13,404,655
With that explanation out of the way, let's continue. Next, we take the number 13,404,655 and divide it by 2:
13,404,655 ÷ 2 = 6,702,327.5
If the quotient is a whole number, then 2 and 6,702,327.5 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 | 13,404,655 | |
| -1 | -13,404,655 |
Now, we try dividing 13,404,655 by 3:
13,404,655 ÷ 3 = 4,468,218.3333
If the quotient is a whole number, then 3 and 4,468,218.3333 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 | 13,404,655 | |
| -1 | -13,404,655 |
Let's try dividing by 4:
13,404,655 ÷ 4 = 3,351,163.75
If the quotient is a whole number, then 4 and 3,351,163.75 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 | 13,404,655 | |
| -1 | 13,404,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 251 | 971 | 1,255 | 2,761 | 4,855 | 10,681 | 13,805 | 53,405 | 243,721 | 1,218,605 | 2,680,931 | 13,404,655 |
| -1 | -5 | -11 | -55 | -251 | -971 | -1,255 | -2,761 | -4,855 | -10,681 | -13,805 | -53,405 | -243,721 | -1,218,605 | -2,680,931 | -13,404,655 |
