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 323,052,421, 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 | 323,052,421 | |
| -1 | -323,052,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,052,421.
Example:
1 x 323,052,421 = 323,052,421
and
-1 x -323,052,421 = 323,052,421
Notice both answers equal 323,052,421
With that explanation out of the way, let's continue. Next, we take the number 323,052,421 and divide it by 2:
323,052,421 ÷ 2 = 161,526,210.5
If the quotient is a whole number, then 2 and 161,526,210.5 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 | 323,052,421 | |
| -1 | -323,052,421 |
Now, we try dividing 323,052,421 by 3:
323,052,421 ÷ 3 = 107,684,140.3333
If the quotient is a whole number, then 3 and 107,684,140.3333 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 | 323,052,421 | |
| -1 | -323,052,421 |
Let's try dividing by 4:
323,052,421 ÷ 4 = 80,763,105.25
If the quotient is a whole number, then 4 and 80,763,105.25 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 | 323,052,421 | |
| -1 | 323,052,421 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 199 | 817 | 1,987 | 3,781 | 8,557 | 37,753 | 85,441 | 162,583 | 395,413 | 1,623,379 | 7,512,847 | 17,002,759 | 323,052,421 |
| -1 | -19 | -43 | -199 | -817 | -1,987 | -3,781 | -8,557 | -37,753 | -85,441 | -162,583 | -395,413 | -1,623,379 | -7,512,847 | -17,002,759 | -323,052,421 |
