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 230,355,545, 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 | 230,355,545 | |
| -1 | -230,355,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,355,545.
Example:
1 x 230,355,545 = 230,355,545
and
-1 x -230,355,545 = 230,355,545
Notice both answers equal 230,355,545
With that explanation out of the way, let's continue. Next, we take the number 230,355,545 and divide it by 2:
230,355,545 ÷ 2 = 115,177,772.5
If the quotient is a whole number, then 2 and 115,177,772.5 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 | 230,355,545 | |
| -1 | -230,355,545 |
Now, we try dividing 230,355,545 by 3:
230,355,545 ÷ 3 = 76,785,181.6667
If the quotient is a whole number, then 3 and 76,785,181.6667 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 | 230,355,545 | |
| -1 | -230,355,545 |
Let's try dividing by 4:
230,355,545 ÷ 4 = 57,588,886.25
If the quotient is a whole number, then 4 and 57,588,886.25 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 | 230,355,545 | |
| -1 | 230,355,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 653 | 3,265 | 4,571 | 10,079 | 22,855 | 50,395 | 70,553 | 352,765 | 6,581,587 | 32,907,935 | 46,071,109 | 230,355,545 |
| -1 | -5 | -7 | -35 | -653 | -3,265 | -4,571 | -10,079 | -22,855 | -50,395 | -70,553 | -352,765 | -6,581,587 | -32,907,935 | -46,071,109 | -230,355,545 |
