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 576,551,311, 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 | 576,551,311 | |
| -1 | -576,551,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 576,551,311.
Example:
1 x 576,551,311 = 576,551,311
and
-1 x -576,551,311 = 576,551,311
Notice both answers equal 576,551,311
With that explanation out of the way, let's continue. Next, we take the number 576,551,311 and divide it by 2:
576,551,311 ÷ 2 = 288,275,655.5
If the quotient is a whole number, then 2 and 288,275,655.5 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 | 576,551,311 | |
| -1 | -576,551,311 |
Now, we try dividing 576,551,311 by 3:
576,551,311 ÷ 3 = 192,183,770.3333
If the quotient is a whole number, then 3 and 192,183,770.3333 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 | 576,551,311 | |
| -1 | -576,551,311 |
Let's try dividing by 4:
576,551,311 ÷ 4 = 144,137,827.75
If the quotient is a whole number, then 4 and 144,137,827.75 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 | 576,551,311 | |
| -1 | 576,551,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 497 | 1,207 | 8,449 | 68,239 | 477,673 | 1,160,063 | 4,844,969 | 8,120,441 | 33,914,783 | 82,364,473 | 576,551,311 |
| -1 | -7 | -17 | -71 | -119 | -497 | -1,207 | -8,449 | -68,239 | -477,673 | -1,160,063 | -4,844,969 | -8,120,441 | -33,914,783 | -82,364,473 | -576,551,311 |
