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 230,032,105, 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 | 230,032,105 | |
| -1 | -230,032,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,032,105.
Example:
1 x 230,032,105 = 230,032,105
and
-1 x -230,032,105 = 230,032,105
Notice both answers equal 230,032,105
With that explanation out of the way, let's continue. Next, we take the number 230,032,105 and divide it by 2:
230,032,105 ÷ 2 = 115,016,052.5
If the quotient is a whole number, then 2 and 115,016,052.5 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 | 230,032,105 | |
| -1 | -230,032,105 |
Now, we try dividing 230,032,105 by 3:
230,032,105 ÷ 3 = 76,677,368.3333
If the quotient is a whole number, then 3 and 76,677,368.3333 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 | 230,032,105 | |
| -1 | -230,032,105 |
Let's try dividing by 4:
230,032,105 ÷ 4 = 57,508,026.25
If the quotient is a whole number, then 4 and 57,508,026.25 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 | 230,032,105 | |
| -1 | 230,032,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 97 | 335 | 485 | 6,499 | 7,079 | 32,495 | 35,395 | 474,293 | 686,663 | 2,371,465 | 3,433,315 | 46,006,421 | 230,032,105 |
| -1 | -5 | -67 | -97 | -335 | -485 | -6,499 | -7,079 | -32,495 | -35,395 | -474,293 | -686,663 | -2,371,465 | -3,433,315 | -46,006,421 | -230,032,105 |
