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 330,234,281, 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 | 330,234,281 | |
| -1 | -330,234,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,234,281.
Example:
1 x 330,234,281 = 330,234,281
and
-1 x -330,234,281 = 330,234,281
Notice both answers equal 330,234,281
With that explanation out of the way, let's continue. Next, we take the number 330,234,281 and divide it by 2:
330,234,281 ÷ 2 = 165,117,140.5
If the quotient is a whole number, then 2 and 165,117,140.5 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 | 330,234,281 | |
| -1 | -330,234,281 |
Now, we try dividing 330,234,281 by 3:
330,234,281 ÷ 3 = 110,078,093.6667
If the quotient is a whole number, then 3 and 110,078,093.6667 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 | 330,234,281 | |
| -1 | -330,234,281 |
Let's try dividing by 4:
330,234,281 ÷ 4 = 82,558,570.25
If the quotient is a whole number, then 4 and 82,558,570.25 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 | 330,234,281 | |
| -1 | 330,234,281 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 43 | 169 | 377 | 559 | 1,247 | 1,567 | 4,901 | 7,267 | 16,211 | 20,371 | 45,443 | 67,381 | 210,743 | 264,823 | 590,759 | 875,953 | 1,954,049 | 7,679,867 | 11,387,389 | 25,402,637 | 330,234,281 |
| -1 | -13 | -29 | -43 | -169 | -377 | -559 | -1,247 | -1,567 | -4,901 | -7,267 | -16,211 | -20,371 | -45,443 | -67,381 | -210,743 | -264,823 | -590,759 | -875,953 | -1,954,049 | -7,679,867 | -11,387,389 | -25,402,637 | -330,234,281 |
