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 255,564,001, 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 | 255,564,001 | |
| -1 | -255,564,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,564,001.
Example:
1 x 255,564,001 = 255,564,001
and
-1 x -255,564,001 = 255,564,001
Notice both answers equal 255,564,001
With that explanation out of the way, let's continue. Next, we take the number 255,564,001 and divide it by 2:
255,564,001 ÷ 2 = 127,782,000.5
If the quotient is a whole number, then 2 and 127,782,000.5 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 | 255,564,001 | |
| -1 | -255,564,001 |
Now, we try dividing 255,564,001 by 3:
255,564,001 ÷ 3 = 85,188,000.3333
If the quotient is a whole number, then 3 and 85,188,000.3333 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 | 255,564,001 | |
| -1 | -255,564,001 |
Let's try dividing by 4:
255,564,001 ÷ 4 = 63,891,000.25
If the quotient is a whole number, then 4 and 63,891,000.25 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 | 255,564,001 | |
| -1 | 255,564,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 997 | 3,329 | 6,979 | 10,967 | 23,303 | 36,619 | 76,769 | 256,333 | 3,319,013 | 23,233,091 | 36,509,143 | 255,564,001 |
| -1 | -7 | -11 | -77 | -997 | -3,329 | -6,979 | -10,967 | -23,303 | -36,619 | -76,769 | -256,333 | -3,319,013 | -23,233,091 | -36,509,143 | -255,564,001 |
