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 587,882,713, 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 | 587,882,713 | |
| -1 | -587,882,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 587,882,713.
Example:
1 x 587,882,713 = 587,882,713
and
-1 x -587,882,713 = 587,882,713
Notice both answers equal 587,882,713
With that explanation out of the way, let's continue. Next, we take the number 587,882,713 and divide it by 2:
587,882,713 ÷ 2 = 293,941,356.5
If the quotient is a whole number, then 2 and 293,941,356.5 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 | 587,882,713 | |
| -1 | -587,882,713 |
Now, we try dividing 587,882,713 by 3:
587,882,713 ÷ 3 = 195,960,904.3333
If the quotient is a whole number, then 3 and 195,960,904.3333 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 | 587,882,713 | |
| -1 | -587,882,713 |
Let's try dividing by 4:
587,882,713 ÷ 4 = 146,970,678.25
If the quotient is a whole number, then 4 and 146,970,678.25 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 | 587,882,713 | |
| -1 | 587,882,713 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 151 | 473 | 1,661 | 6,493 | 8,231 | 71,423 | 90,541 | 353,933 | 1,242,881 | 3,893,263 | 13,671,691 | 53,443,883 | 587,882,713 |
| -1 | -11 | -43 | -151 | -473 | -1,661 | -6,493 | -8,231 | -71,423 | -90,541 | -353,933 | -1,242,881 | -3,893,263 | -13,671,691 | -53,443,883 | -587,882,713 |
