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 234,310,223, 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 | 234,310,223 | |
| -1 | -234,310,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,310,223.
Example:
1 x 234,310,223 = 234,310,223
and
-1 x -234,310,223 = 234,310,223
Notice both answers equal 234,310,223
With that explanation out of the way, let's continue. Next, we take the number 234,310,223 and divide it by 2:
234,310,223 ÷ 2 = 117,155,111.5
If the quotient is a whole number, then 2 and 117,155,111.5 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 | 234,310,223 | |
| -1 | -234,310,223 |
Now, we try dividing 234,310,223 by 3:
234,310,223 ÷ 3 = 78,103,407.6667
If the quotient is a whole number, then 3 and 78,103,407.6667 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 | 234,310,223 | |
| -1 | -234,310,223 |
Let's try dividing by 4:
234,310,223 ÷ 4 = 58,577,555.75
If the quotient is a whole number, then 4 and 58,577,555.75 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 | 234,310,223 | |
| -1 | 234,310,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 76,597 | 536,179 | 1,455,343 | 1,761,731 | 10,187,401 | 12,332,117 | 33,472,889 | 234,310,223 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -76,597 | -536,179 | -1,455,343 | -1,761,731 | -10,187,401 | -12,332,117 | -33,472,889 | -234,310,223 |
