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 255,011,435, 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 | 255,011,435 | |
| -1 | -255,011,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,011,435.
Example:
1 x 255,011,435 = 255,011,435
and
-1 x -255,011,435 = 255,011,435
Notice both answers equal 255,011,435
With that explanation out of the way, let's continue. Next, we take the number 255,011,435 and divide it by 2:
255,011,435 ÷ 2 = 127,505,717.5
If the quotient is a whole number, then 2 and 127,505,717.5 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 | 255,011,435 | |
| -1 | -255,011,435 |
Now, we try dividing 255,011,435 by 3:
255,011,435 ÷ 3 = 85,003,811.6667
If the quotient is a whole number, then 3 and 85,003,811.6667 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 | 255,011,435 | |
| -1 | -255,011,435 |
Let's try dividing by 4:
255,011,435 ÷ 4 = 63,752,858.75
If the quotient is a whole number, then 4 and 63,752,858.75 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 | 255,011,435 | |
| -1 | 255,011,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 211 | 245 | 1,055 | 1,477 | 4,933 | 7,385 | 10,339 | 24,665 | 34,531 | 51,695 | 172,655 | 241,717 | 1,040,863 | 1,208,585 | 5,204,315 | 7,286,041 | 36,430,205 | 51,002,287 | 255,011,435 |
| -1 | -5 | -7 | -35 | -49 | -211 | -245 | -1,055 | -1,477 | -4,933 | -7,385 | -10,339 | -24,665 | -34,531 | -51,695 | -172,655 | -241,717 | -1,040,863 | -1,208,585 | -5,204,315 | -7,286,041 | -36,430,205 | -51,002,287 | -255,011,435 |
