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 576,520,135, 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 | 576,520,135 | |
| -1 | -576,520,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 576,520,135.
Example:
1 x 576,520,135 = 576,520,135
and
-1 x -576,520,135 = 576,520,135
Notice both answers equal 576,520,135
With that explanation out of the way, let's continue. Next, we take the number 576,520,135 and divide it by 2:
576,520,135 ÷ 2 = 288,260,067.5
If the quotient is a whole number, then 2 and 288,260,067.5 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 | 576,520,135 | |
| -1 | -576,520,135 |
Now, we try dividing 576,520,135 by 3:
576,520,135 ÷ 3 = 192,173,378.3333
If the quotient is a whole number, then 3 and 192,173,378.3333 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 | 576,520,135 | |
| -1 | -576,520,135 |
Let's try dividing by 4:
576,520,135 ÷ 4 = 144,130,033.75
If the quotient is a whole number, then 4 and 144,130,033.75 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 | 576,520,135 | |
| -1 | 576,520,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 141,131 | 705,655 | 2,681,489 | 6,068,633 | 13,407,445 | 30,343,165 | 115,304,027 | 576,520,135 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -141,131 | -705,655 | -2,681,489 | -6,068,633 | -13,407,445 | -30,343,165 | -115,304,027 | -576,520,135 |
