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 230,321,045, 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 | 230,321,045 | |
| -1 | -230,321,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,321,045.
Example:
1 x 230,321,045 = 230,321,045
and
-1 x -230,321,045 = 230,321,045
Notice both answers equal 230,321,045
With that explanation out of the way, let's continue. Next, we take the number 230,321,045 and divide it by 2:
230,321,045 ÷ 2 = 115,160,522.5
If the quotient is a whole number, then 2 and 115,160,522.5 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 | 230,321,045 | |
| -1 | -230,321,045 |
Now, we try dividing 230,321,045 by 3:
230,321,045 ÷ 3 = 76,773,681.6667
If the quotient is a whole number, then 3 and 76,773,681.6667 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 | 230,321,045 | |
| -1 | -230,321,045 |
Let's try dividing by 4:
230,321,045 ÷ 4 = 57,580,261.25
If the quotient is a whole number, then 4 and 57,580,261.25 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 | 230,321,045 | |
| -1 | 230,321,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 797 | 1,993 | 3,985 | 9,965 | 23,113 | 57,797 | 115,565 | 288,985 | 1,588,421 | 7,942,105 | 46,064,209 | 230,321,045 |
| -1 | -5 | -29 | -145 | -797 | -1,993 | -3,985 | -9,965 | -23,113 | -57,797 | -115,565 | -288,985 | -1,588,421 | -7,942,105 | -46,064,209 | -230,321,045 |
