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 330,000,223, 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 | 330,000,223 | |
| -1 | -330,000,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,000,223.
Example:
1 x 330,000,223 = 330,000,223
and
-1 x -330,000,223 = 330,000,223
Notice both answers equal 330,000,223
With that explanation out of the way, let's continue. Next, we take the number 330,000,223 and divide it by 2:
330,000,223 ÷ 2 = 165,000,111.5
If the quotient is a whole number, then 2 and 165,000,111.5 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 | 330,000,223 | |
| -1 | -330,000,223 |
Now, we try dividing 330,000,223 by 3:
330,000,223 ÷ 3 = 110,000,074.3333
If the quotient is a whole number, then 3 and 110,000,074.3333 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 | 330,000,223 | |
| -1 | -330,000,223 |
Let's try dividing by 4:
330,000,223 ÷ 4 = 82,500,055.75
If the quotient is a whole number, then 4 and 82,500,055.75 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 | 330,000,223 | |
| -1 | 330,000,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 271 | 511 | 1,897 | 2,383 | 16,681 | 19,783 | 138,481 | 173,959 | 645,793 | 1,217,713 | 4,520,551 | 47,142,889 | 330,000,223 |
| -1 | -7 | -73 | -271 | -511 | -1,897 | -2,383 | -16,681 | -19,783 | -138,481 | -173,959 | -645,793 | -1,217,713 | -4,520,551 | -47,142,889 | -330,000,223 |
