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 230,436,173, 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 | 230,436,173 | |
| -1 | -230,436,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,436,173.
Example:
1 x 230,436,173 = 230,436,173
and
-1 x -230,436,173 = 230,436,173
Notice both answers equal 230,436,173
With that explanation out of the way, let's continue. Next, we take the number 230,436,173 and divide it by 2:
230,436,173 ÷ 2 = 115,218,086.5
If the quotient is a whole number, then 2 and 115,218,086.5 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 | 230,436,173 | |
| -1 | -230,436,173 |
Now, we try dividing 230,436,173 by 3:
230,436,173 ÷ 3 = 76,812,057.6667
If the quotient is a whole number, then 3 and 76,812,057.6667 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 | 230,436,173 | |
| -1 | -230,436,173 |
Let's try dividing by 4:
230,436,173 ÷ 4 = 57,609,043.25
If the quotient is a whole number, then 4 and 57,609,043.25 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 | 230,436,173 | |
| -1 | 230,436,173 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 173 | 187 | 289 | 419 | 1,903 | 2,941 | 3,179 | 4,609 | 7,123 | 32,351 | 49,997 | 72,487 | 78,353 | 121,091 | 549,967 | 797,357 | 1,232,279 | 1,332,001 | 13,555,069 | 20,948,743 | 230,436,173 |
| -1 | -11 | -17 | -173 | -187 | -289 | -419 | -1,903 | -2,941 | -3,179 | -4,609 | -7,123 | -32,351 | -49,997 | -72,487 | -78,353 | -121,091 | -549,967 | -797,357 | -1,232,279 | -1,332,001 | -13,555,069 | -20,948,743 | -230,436,173 |
