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 230,342,347, 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 | 230,342,347 | |
| -1 | -230,342,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,342,347.
Example:
1 x 230,342,347 = 230,342,347
and
-1 x -230,342,347 = 230,342,347
Notice both answers equal 230,342,347
With that explanation out of the way, let's continue. Next, we take the number 230,342,347 and divide it by 2:
230,342,347 ÷ 2 = 115,171,173.5
If the quotient is a whole number, then 2 and 115,171,173.5 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 | 230,342,347 | |
| -1 | -230,342,347 |
Now, we try dividing 230,342,347 by 3:
230,342,347 ÷ 3 = 76,780,782.3333
If the quotient is a whole number, then 3 and 76,780,782.3333 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 | 230,342,347 | |
| -1 | -230,342,347 |
Let's try dividing by 4:
230,342,347 ÷ 4 = 57,585,586.75
If the quotient is a whole number, then 4 and 57,585,586.75 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 | 230,342,347 | |
| -1 | 230,342,347 |
If you did it right, you will end up with this table:
| 1 | 47 | 83 | 137 | 431 | 3,901 | 6,439 | 11,371 | 20,257 | 35,773 | 59,047 | 534,437 | 1,681,331 | 2,775,209 | 4,900,901 | 230,342,347 |
| -1 | -47 | -83 | -137 | -431 | -3,901 | -6,439 | -11,371 | -20,257 | -35,773 | -59,047 | -534,437 | -1,681,331 | -2,775,209 | -4,900,901 | -230,342,347 |
