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 404,323,135, 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 | 404,323,135 | |
| -1 | -404,323,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,323,135.
Example:
1 x 404,323,135 = 404,323,135
and
-1 x -404,323,135 = 404,323,135
Notice both answers equal 404,323,135
With that explanation out of the way, let's continue. Next, we take the number 404,323,135 and divide it by 2:
404,323,135 ÷ 2 = 202,161,567.5
If the quotient is a whole number, then 2 and 202,161,567.5 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 | 404,323,135 | |
| -1 | -404,323,135 |
Now, we try dividing 404,323,135 by 3:
404,323,135 ÷ 3 = 134,774,378.3333
If the quotient is a whole number, then 3 and 134,774,378.3333 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 | 404,323,135 | |
| -1 | -404,323,135 |
Let's try dividing by 4:
404,323,135 ÷ 4 = 101,080,783.75
If the quotient is a whole number, then 4 and 101,080,783.75 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 | 404,323,135 | |
| -1 | 404,323,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,721 | 2,473 | 8,605 | 12,365 | 32,699 | 46,987 | 163,495 | 234,935 | 4,256,033 | 21,280,165 | 80,864,627 | 404,323,135 |
| -1 | -5 | -19 | -95 | -1,721 | -2,473 | -8,605 | -12,365 | -32,699 | -46,987 | -163,495 | -234,935 | -4,256,033 | -21,280,165 | -80,864,627 | -404,323,135 |
