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 321,411,299, 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 | 321,411,299 | |
| -1 | -321,411,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,411,299.
Example:
1 x 321,411,299 = 321,411,299
and
-1 x -321,411,299 = 321,411,299
Notice both answers equal 321,411,299
With that explanation out of the way, let's continue. Next, we take the number 321,411,299 and divide it by 2:
321,411,299 ÷ 2 = 160,705,649.5
If the quotient is a whole number, then 2 and 160,705,649.5 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 | 321,411,299 | |
| -1 | -321,411,299 |
Now, we try dividing 321,411,299 by 3:
321,411,299 ÷ 3 = 107,137,099.6667
If the quotient is a whole number, then 3 and 107,137,099.6667 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 | 321,411,299 | |
| -1 | -321,411,299 |
Let's try dividing by 4:
321,411,299 ÷ 4 = 80,352,824.75
If the quotient is a whole number, then 4 and 80,352,824.75 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 | 321,411,299 | |
| -1 | 321,411,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 457 | 3,761 | 5,027 | 7,769 | 41,371 | 63,937 | 85,459 | 703,307 | 1,718,777 | 18,906,547 | 29,219,209 | 321,411,299 |
| -1 | -11 | -17 | -187 | -457 | -3,761 | -5,027 | -7,769 | -41,371 | -63,937 | -85,459 | -703,307 | -1,718,777 | -18,906,547 | -29,219,209 | -321,411,299 |
