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 13,366,255, 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 | 13,366,255 | |
| -1 | -13,366,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,366,255.
Example:
1 x 13,366,255 = 13,366,255
and
-1 x -13,366,255 = 13,366,255
Notice both answers equal 13,366,255
With that explanation out of the way, let's continue. Next, we take the number 13,366,255 and divide it by 2:
13,366,255 ÷ 2 = 6,683,127.5
If the quotient is a whole number, then 2 and 6,683,127.5 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 | 13,366,255 | |
| -1 | -13,366,255 |
Now, we try dividing 13,366,255 by 3:
13,366,255 ÷ 3 = 4,455,418.3333
If the quotient is a whole number, then 3 and 4,455,418.3333 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 | 13,366,255 | |
| -1 | -13,366,255 |
Let's try dividing by 4:
13,366,255 ÷ 4 = 3,341,563.75
If the quotient is a whole number, then 4 and 3,341,563.75 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 | 13,366,255 | |
| -1 | 13,366,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 521 | 733 | 2,605 | 3,647 | 3,665 | 5,131 | 18,235 | 25,655 | 381,893 | 1,909,465 | 2,673,251 | 13,366,255 |
| -1 | -5 | -7 | -35 | -521 | -733 | -2,605 | -3,647 | -3,665 | -5,131 | -18,235 | -25,655 | -381,893 | -1,909,465 | -2,673,251 | -13,366,255 |
