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 573,023,815, 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 | 573,023,815 | |
| -1 | -573,023,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 573,023,815.
Example:
1 x 573,023,815 = 573,023,815
and
-1 x -573,023,815 = 573,023,815
Notice both answers equal 573,023,815
With that explanation out of the way, let's continue. Next, we take the number 573,023,815 and divide it by 2:
573,023,815 ÷ 2 = 286,511,907.5
If the quotient is a whole number, then 2 and 286,511,907.5 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 | 573,023,815 | |
| -1 | -573,023,815 |
Now, we try dividing 573,023,815 by 3:
573,023,815 ÷ 3 = 191,007,938.3333
If the quotient is a whole number, then 3 and 191,007,938.3333 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 | 573,023,815 | |
| -1 | -573,023,815 |
Let's try dividing by 4:
573,023,815 ÷ 4 = 143,255,953.75
If the quotient is a whole number, then 4 and 143,255,953.75 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 | 573,023,815 | |
| -1 | 573,023,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 1,259,393 | 6,296,965 | 8,815,751 | 16,372,109 | 44,078,755 | 81,860,545 | 114,604,763 | 573,023,815 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -1,259,393 | -6,296,965 | -8,815,751 | -16,372,109 | -44,078,755 | -81,860,545 | -114,604,763 | -573,023,815 |
