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 230,026,811, 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 | 230,026,811 | |
| -1 | -230,026,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,026,811.
Example:
1 x 230,026,811 = 230,026,811
and
-1 x -230,026,811 = 230,026,811
Notice both answers equal 230,026,811
With that explanation out of the way, let's continue. Next, we take the number 230,026,811 and divide it by 2:
230,026,811 ÷ 2 = 115,013,405.5
If the quotient is a whole number, then 2 and 115,013,405.5 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 | 230,026,811 | |
| -1 | -230,026,811 |
Now, we try dividing 230,026,811 by 3:
230,026,811 ÷ 3 = 76,675,603.6667
If the quotient is a whole number, then 3 and 76,675,603.6667 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 | 230,026,811 | |
| -1 | -230,026,811 |
Let's try dividing by 4:
230,026,811 ÷ 4 = 57,506,702.75
If the quotient is a whole number, then 4 and 57,506,702.75 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 | 230,026,811 | |
| -1 | 230,026,811 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 307 | 2,149 | 3,691 | 8,903 | 25,837 | 62,321 | 107,039 | 749,273 | 1,133,137 | 7,931,959 | 32,860,973 | 230,026,811 |
| -1 | -7 | -29 | -203 | -307 | -2,149 | -3,691 | -8,903 | -25,837 | -62,321 | -107,039 | -749,273 | -1,133,137 | -7,931,959 | -32,860,973 | -230,026,811 |
