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 322,011,235, 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 | 322,011,235 | |
| -1 | -322,011,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,011,235.
Example:
1 x 322,011,235 = 322,011,235
and
-1 x -322,011,235 = 322,011,235
Notice both answers equal 322,011,235
With that explanation out of the way, let's continue. Next, we take the number 322,011,235 and divide it by 2:
322,011,235 ÷ 2 = 161,005,617.5
If the quotient is a whole number, then 2 and 161,005,617.5 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 | 322,011,235 | |
| -1 | -322,011,235 |
Now, we try dividing 322,011,235 by 3:
322,011,235 ÷ 3 = 107,337,078.3333
If the quotient is a whole number, then 3 and 107,337,078.3333 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 | 322,011,235 | |
| -1 | -322,011,235 |
Let's try dividing by 4:
322,011,235 ÷ 4 = 80,502,808.75
If the quotient is a whole number, then 4 and 80,502,808.75 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 | 322,011,235 | |
| -1 | 322,011,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 707,717 | 3,538,585 | 4,954,019 | 9,200,321 | 24,770,095 | 46,001,605 | 64,402,247 | 322,011,235 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -707,717 | -3,538,585 | -4,954,019 | -9,200,321 | -24,770,095 | -46,001,605 | -64,402,247 | -322,011,235 |
