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 255,054,163, 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 | 255,054,163 | |
| -1 | -255,054,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,054,163.
Example:
1 x 255,054,163 = 255,054,163
and
-1 x -255,054,163 = 255,054,163
Notice both answers equal 255,054,163
With that explanation out of the way, let's continue. Next, we take the number 255,054,163 and divide it by 2:
255,054,163 ÷ 2 = 127,527,081.5
If the quotient is a whole number, then 2 and 127,527,081.5 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 | 255,054,163 | |
| -1 | -255,054,163 |
Now, we try dividing 255,054,163 by 3:
255,054,163 ÷ 3 = 85,018,054.3333
If the quotient is a whole number, then 3 and 85,018,054.3333 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 | 255,054,163 | |
| -1 | -255,054,163 |
Let's try dividing by 4:
255,054,163 ÷ 4 = 63,763,540.75
If the quotient is a whole number, then 4 and 63,763,540.75 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 | 255,054,163 | |
| -1 | 255,054,163 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 431 | 637 | 929 | 3,017 | 5,603 | 6,503 | 12,077 | 21,119 | 39,221 | 45,521 | 84,539 | 274,547 | 400,399 | 591,773 | 2,802,793 | 5,205,187 | 19,619,551 | 36,436,309 | 255,054,163 |
| -1 | -7 | -13 | -49 | -91 | -431 | -637 | -929 | -3,017 | -5,603 | -6,503 | -12,077 | -21,119 | -39,221 | -45,521 | -84,539 | -274,547 | -400,399 | -591,773 | -2,802,793 | -5,205,187 | -19,619,551 | -36,436,309 | -255,054,163 |
