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 404,022,323, 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 | 404,022,323 | |
| -1 | -404,022,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,022,323.
Example:
1 x 404,022,323 = 404,022,323
and
-1 x -404,022,323 = 404,022,323
Notice both answers equal 404,022,323
With that explanation out of the way, let's continue. Next, we take the number 404,022,323 and divide it by 2:
404,022,323 ÷ 2 = 202,011,161.5
If the quotient is a whole number, then 2 and 202,011,161.5 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 | 404,022,323 | |
| -1 | -404,022,323 |
Now, we try dividing 404,022,323 by 3:
404,022,323 ÷ 3 = 134,674,107.6667
If the quotient is a whole number, then 3 and 134,674,107.6667 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 | 404,022,323 | |
| -1 | -404,022,323 |
Let's try dividing by 4:
404,022,323 ÷ 4 = 101,005,580.75
If the quotient is a whole number, then 4 and 101,005,580.75 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 | 404,022,323 | |
| -1 | 404,022,323 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 449 | 697 | 1,291 | 7,633 | 18,409 | 21,947 | 52,931 | 312,953 | 579,659 | 899,827 | 9,854,203 | 23,766,019 | 404,022,323 |
| -1 | -17 | -41 | -449 | -697 | -1,291 | -7,633 | -18,409 | -21,947 | -52,931 | -312,953 | -579,659 | -899,827 | -9,854,203 | -23,766,019 | -404,022,323 |
