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 322,547,071, 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 | 322,547,071 | |
| -1 | -322,547,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,547,071.
Example:
1 x 322,547,071 = 322,547,071
and
-1 x -322,547,071 = 322,547,071
Notice both answers equal 322,547,071
With that explanation out of the way, let's continue. Next, we take the number 322,547,071 and divide it by 2:
322,547,071 ÷ 2 = 161,273,535.5
If the quotient is a whole number, then 2 and 161,273,535.5 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 | 322,547,071 | |
| -1 | -322,547,071 |
Now, we try dividing 322,547,071 by 3:
322,547,071 ÷ 3 = 107,515,690.3333
If the quotient is a whole number, then 3 and 107,515,690.3333 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 | 322,547,071 | |
| -1 | -322,547,071 |
Let's try dividing by 4:
322,547,071 ÷ 4 = 80,636,767.75
If the quotient is a whole number, then 4 and 80,636,767.75 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 | 322,547,071 | |
| -1 | 322,547,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,187 | 3,529 | 8,309 | 13,057 | 24,703 | 38,819 | 91,399 | 271,733 | 4,188,923 | 29,322,461 | 46,078,153 | 322,547,071 |
| -1 | -7 | -11 | -77 | -1,187 | -3,529 | -8,309 | -13,057 | -24,703 | -38,819 | -91,399 | -271,733 | -4,188,923 | -29,322,461 | -46,078,153 | -322,547,071 |
