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 384,307, 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 | 384,307 | |
| -1 | -384,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 384,307.
Example:
1 x 384,307 = 384,307
and
-1 x -384,307 = 384,307
Notice both answers equal 384,307
With that explanation out of the way, let's continue. Next, we take the number 384,307 and divide it by 2:
384,307 ÷ 2 = 192,153.5
If the quotient is a whole number, then 2 and 192,153.5 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 | 384,307 | |
| -1 | -384,307 |
Now, we try dividing 384,307 by 3:
384,307 ÷ 3 = 128,102.3333
If the quotient is a whole number, then 3 and 128,102.3333 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 | 384,307 | |
| -1 | -384,307 |
Let's try dividing by 4:
384,307 ÷ 4 = 96,076.75
If the quotient is a whole number, then 4 and 96,076.75 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 | 384,307 | |
| -1 | 384,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 31 | 49 | 77 | 161 | 217 | 253 | 341 | 539 | 713 | 1,127 | 1,519 | 1,771 | 2,387 | 4,991 | 7,843 | 12,397 | 16,709 | 34,937 | 54,901 | 384,307 |
| -1 | -7 | -11 | -23 | -31 | -49 | -77 | -161 | -217 | -253 | -341 | -539 | -713 | -1,127 | -1,519 | -1,771 | -2,387 | -4,991 | -7,843 | -12,397 | -16,709 | -34,937 | -54,901 | -384,307 |
