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 533,557,631, 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 | 533,557,631 | |
| -1 | -533,557,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,557,631.
Example:
1 x 533,557,631 = 533,557,631
and
-1 x -533,557,631 = 533,557,631
Notice both answers equal 533,557,631
With that explanation out of the way, let's continue. Next, we take the number 533,557,631 and divide it by 2:
533,557,631 ÷ 2 = 266,778,815.5
If the quotient is a whole number, then 2 and 266,778,815.5 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 | 533,557,631 | |
| -1 | -533,557,631 |
Now, we try dividing 533,557,631 by 3:
533,557,631 ÷ 3 = 177,852,543.6667
If the quotient is a whole number, then 3 and 177,852,543.6667 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 | 533,557,631 | |
| -1 | -533,557,631 |
Let's try dividing by 4:
533,557,631 ÷ 4 = 133,389,407.75
If the quotient is a whole number, then 4 and 133,389,407.75 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 | 533,557,631 | |
| -1 | 533,557,631 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 43 | 493 | 731 | 1,247 | 21,199 | 25,169 | 427,873 | 729,901 | 1,082,267 | 12,408,317 | 18,398,539 | 31,385,743 | 533,557,631 |
| -1 | -17 | -29 | -43 | -493 | -731 | -1,247 | -21,199 | -25,169 | -427,873 | -729,901 | -1,082,267 | -12,408,317 | -18,398,539 | -31,385,743 | -533,557,631 |
