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 13,573,255, 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 | 13,573,255 | |
| -1 | -13,573,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,573,255.
Example:
1 x 13,573,255 = 13,573,255
and
-1 x -13,573,255 = 13,573,255
Notice both answers equal 13,573,255
With that explanation out of the way, let's continue. Next, we take the number 13,573,255 and divide it by 2:
13,573,255 ÷ 2 = 6,786,627.5
If the quotient is a whole number, then 2 and 6,786,627.5 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 | 13,573,255 | |
| -1 | -13,573,255 |
Now, we try dividing 13,573,255 by 3:
13,573,255 ÷ 3 = 4,524,418.3333
If the quotient is a whole number, then 3 and 4,524,418.3333 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 | 13,573,255 | |
| -1 | -13,573,255 |
Let's try dividing by 4:
13,573,255 ÷ 4 = 3,393,313.75
If the quotient is a whole number, then 4 and 3,393,313.75 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 | 13,573,255 | |
| -1 | 13,573,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 73 | 205 | 365 | 907 | 2,993 | 4,535 | 14,965 | 37,187 | 66,211 | 185,935 | 331,055 | 2,714,651 | 13,573,255 |
| -1 | -5 | -41 | -73 | -205 | -365 | -907 | -2,993 | -4,535 | -14,965 | -37,187 | -66,211 | -185,935 | -331,055 | -2,714,651 | -13,573,255 |
