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 230,071,361, 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 | 230,071,361 | |
| -1 | -230,071,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,071,361.
Example:
1 x 230,071,361 = 230,071,361
and
-1 x -230,071,361 = 230,071,361
Notice both answers equal 230,071,361
With that explanation out of the way, let's continue. Next, we take the number 230,071,361 and divide it by 2:
230,071,361 ÷ 2 = 115,035,680.5
If the quotient is a whole number, then 2 and 115,035,680.5 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 | 230,071,361 | |
| -1 | -230,071,361 |
Now, we try dividing 230,071,361 by 3:
230,071,361 ÷ 3 = 76,690,453.6667
If the quotient is a whole number, then 3 and 76,690,453.6667 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 | 230,071,361 | |
| -1 | -230,071,361 |
Let's try dividing by 4:
230,071,361 ÷ 4 = 57,517,840.25
If the quotient is a whole number, then 4 and 57,517,840.25 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 | 230,071,361 | |
| -1 | 230,071,361 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 137 | 169 | 247 | 523 | 1,781 | 2,603 | 3,211 | 6,799 | 9,937 | 23,153 | 33,839 | 71,651 | 88,387 | 129,181 | 439,907 | 931,463 | 1,361,369 | 1,679,353 | 12,109,019 | 17,697,797 | 230,071,361 |
| -1 | -13 | -19 | -137 | -169 | -247 | -523 | -1,781 | -2,603 | -3,211 | -6,799 | -9,937 | -23,153 | -33,839 | -71,651 | -88,387 | -129,181 | -439,907 | -931,463 | -1,361,369 | -1,679,353 | -12,109,019 | -17,697,797 | -230,071,361 |
