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 324,341,423, 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 | 324,341,423 | |
| -1 | -324,341,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,341,423.
Example:
1 x 324,341,423 = 324,341,423
and
-1 x -324,341,423 = 324,341,423
Notice both answers equal 324,341,423
With that explanation out of the way, let's continue. Next, we take the number 324,341,423 and divide it by 2:
324,341,423 ÷ 2 = 162,170,711.5
If the quotient is a whole number, then 2 and 162,170,711.5 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 | 324,341,423 | |
| -1 | -324,341,423 |
Now, we try dividing 324,341,423 by 3:
324,341,423 ÷ 3 = 108,113,807.6667
If the quotient is a whole number, then 3 and 108,113,807.6667 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 | 324,341,423 | |
| -1 | -324,341,423 |
Let's try dividing by 4:
324,341,423 ÷ 4 = 81,085,355.75
If the quotient is a whole number, then 4 and 81,085,355.75 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 | 324,341,423 | |
| -1 | 324,341,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 69,467 | 486,269 | 1,597,741 | 2,014,543 | 11,184,187 | 14,101,801 | 46,334,489 | 324,341,423 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -69,467 | -486,269 | -1,597,741 | -2,014,543 | -11,184,187 | -14,101,801 | -46,334,489 | -324,341,423 |
