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 577,330,721, 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 | 577,330,721 | |
| -1 | -577,330,721 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 577,330,721.
Example:
1 x 577,330,721 = 577,330,721
and
-1 x -577,330,721 = 577,330,721
Notice both answers equal 577,330,721
With that explanation out of the way, let's continue. Next, we take the number 577,330,721 and divide it by 2:
577,330,721 ÷ 2 = 288,665,360.5
If the quotient is a whole number, then 2 and 288,665,360.5 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 | 577,330,721 | |
| -1 | -577,330,721 |
Now, we try dividing 577,330,721 by 3:
577,330,721 ÷ 3 = 192,443,573.6667
If the quotient is a whole number, then 3 and 192,443,573.6667 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 | 577,330,721 | |
| -1 | -577,330,721 |
Let's try dividing by 4:
577,330,721 ÷ 4 = 144,332,680.25
If the quotient is a whole number, then 4 and 144,332,680.25 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 | 577,330,721 | |
| -1 | 577,330,721 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 223 | 407 | 2,453 | 6,361 | 8,251 | 69,971 | 90,761 | 235,357 | 1,418,503 | 2,588,927 | 15,603,533 | 52,484,611 | 577,330,721 |
| -1 | -11 | -37 | -223 | -407 | -2,453 | -6,361 | -8,251 | -69,971 | -90,761 | -235,357 | -1,418,503 | -2,588,927 | -15,603,533 | -52,484,611 | -577,330,721 |
