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 533,721,425, 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 | 533,721,425 | |
| -1 | -533,721,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,721,425.
Example:
1 x 533,721,425 = 533,721,425
and
-1 x -533,721,425 = 533,721,425
Notice both answers equal 533,721,425
With that explanation out of the way, let's continue. Next, we take the number 533,721,425 and divide it by 2:
533,721,425 ÷ 2 = 266,860,712.5
If the quotient is a whole number, then 2 and 266,860,712.5 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 | 533,721,425 | |
| -1 | -533,721,425 |
Now, we try dividing 533,721,425 by 3:
533,721,425 ÷ 3 = 177,907,141.6667
If the quotient is a whole number, then 3 and 177,907,141.6667 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 | 533,721,425 | |
| -1 | -533,721,425 |
Let's try dividing by 4:
533,721,425 ÷ 4 = 133,430,356.25
If the quotient is a whole number, then 4 and 133,430,356.25 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 | 533,721,425 | |
| -1 | 533,721,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 235 | 1,175 | 454,231 | 2,271,155 | 11,355,775 | 21,348,857 | 106,744,285 | 533,721,425 |
| -1 | -5 | -25 | -47 | -235 | -1,175 | -454,231 | -2,271,155 | -11,355,775 | -21,348,857 | -106,744,285 | -533,721,425 |
