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 533,740,123, 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 | 533,740,123 | |
| -1 | -533,740,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,740,123.
Example:
1 x 533,740,123 = 533,740,123
and
-1 x -533,740,123 = 533,740,123
Notice both answers equal 533,740,123
With that explanation out of the way, let's continue. Next, we take the number 533,740,123 and divide it by 2:
533,740,123 ÷ 2 = 266,870,061.5
If the quotient is a whole number, then 2 and 266,870,061.5 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 | 533,740,123 | |
| -1 | -533,740,123 |
Now, we try dividing 533,740,123 by 3:
533,740,123 ÷ 3 = 177,913,374.3333
If the quotient is a whole number, then 3 and 177,913,374.3333 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 | 533,740,123 | |
| -1 | -533,740,123 |
Let's try dividing by 4:
533,740,123 ÷ 4 = 133,435,030.75
If the quotient is a whole number, then 4 and 133,435,030.75 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 | 533,740,123 | |
| -1 | 533,740,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 139 | 301 | 973 | 5,977 | 12,757 | 41,839 | 89,299 | 548,551 | 1,773,223 | 3,839,857 | 12,412,561 | 76,248,589 | 533,740,123 |
| -1 | -7 | -43 | -139 | -301 | -973 | -5,977 | -12,757 | -41,839 | -89,299 | -548,551 | -1,773,223 | -3,839,857 | -12,412,561 | -76,248,589 | -533,740,123 |
