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 231,434,885, 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 | 231,434,885 | |
| -1 | -231,434,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,434,885.
Example:
1 x 231,434,885 = 231,434,885
and
-1 x -231,434,885 = 231,434,885
Notice both answers equal 231,434,885
With that explanation out of the way, let's continue. Next, we take the number 231,434,885 and divide it by 2:
231,434,885 ÷ 2 = 115,717,442.5
If the quotient is a whole number, then 2 and 115,717,442.5 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 | 231,434,885 | |
| -1 | -231,434,885 |
Now, we try dividing 231,434,885 by 3:
231,434,885 ÷ 3 = 77,144,961.6667
If the quotient is a whole number, then 3 and 77,144,961.6667 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 | 231,434,885 | |
| -1 | -231,434,885 |
Let's try dividing by 4:
231,434,885 ÷ 4 = 57,858,721.25
If the quotient is a whole number, then 4 and 57,858,721.25 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 | 231,434,885 | |
| -1 | 231,434,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 277 | 605 | 1,381 | 1,385 | 3,047 | 6,905 | 15,191 | 15,235 | 33,517 | 75,955 | 167,101 | 167,585 | 382,537 | 835,505 | 1,912,685 | 4,207,907 | 21,039,535 | 46,286,977 | 231,434,885 |
| -1 | -5 | -11 | -55 | -121 | -277 | -605 | -1,381 | -1,385 | -3,047 | -6,905 | -15,191 | -15,235 | -33,517 | -75,955 | -167,101 | -167,585 | -382,537 | -835,505 | -1,912,685 | -4,207,907 | -21,039,535 | -46,286,977 | -231,434,885 |
