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 576,542,681, 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 | 576,542,681 | |
| -1 | -576,542,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 576,542,681.
Example:
1 x 576,542,681 = 576,542,681
and
-1 x -576,542,681 = 576,542,681
Notice both answers equal 576,542,681
With that explanation out of the way, let's continue. Next, we take the number 576,542,681 and divide it by 2:
576,542,681 ÷ 2 = 288,271,340.5
If the quotient is a whole number, then 2 and 288,271,340.5 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 | 576,542,681 | |
| -1 | -576,542,681 |
Now, we try dividing 576,542,681 by 3:
576,542,681 ÷ 3 = 192,180,893.6667
If the quotient is a whole number, then 3 and 192,180,893.6667 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 | 576,542,681 | |
| -1 | -576,542,681 |
Let's try dividing by 4:
576,542,681 ÷ 4 = 144,135,670.25
If the quotient is a whole number, then 4 and 144,135,670.25 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 | 576,542,681 | |
| -1 | 576,542,681 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 341 | 403 | 4,433 | 130,057 | 1,430,627 | 1,690,741 | 4,031,767 | 18,598,151 | 44,349,437 | 52,412,971 | 576,542,681 |
| -1 | -11 | -13 | -31 | -143 | -341 | -403 | -4,433 | -130,057 | -1,430,627 | -1,690,741 | -4,031,767 | -18,598,151 | -44,349,437 | -52,412,971 | -576,542,681 |
