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 321,105,325, 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 | 321,105,325 | |
| -1 | -321,105,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,105,325.
Example:
1 x 321,105,325 = 321,105,325
and
-1 x -321,105,325 = 321,105,325
Notice both answers equal 321,105,325
With that explanation out of the way, let's continue. Next, we take the number 321,105,325 and divide it by 2:
321,105,325 ÷ 2 = 160,552,662.5
If the quotient is a whole number, then 2 and 160,552,662.5 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 | 321,105,325 | |
| -1 | -321,105,325 |
Now, we try dividing 321,105,325 by 3:
321,105,325 ÷ 3 = 107,035,108.3333
If the quotient is a whole number, then 3 and 107,035,108.3333 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 | 321,105,325 | |
| -1 | -321,105,325 |
Let's try dividing by 4:
321,105,325 ÷ 4 = 80,276,331.25
If the quotient is a whole number, then 4 and 80,276,331.25 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 | 321,105,325 | |
| -1 | 321,105,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 89 | 277 | 445 | 521 | 1,385 | 2,225 | 2,605 | 6,925 | 13,025 | 24,653 | 46,369 | 123,265 | 144,317 | 231,845 | 616,325 | 721,585 | 1,159,225 | 3,607,925 | 12,844,213 | 64,221,065 | 321,105,325 |
| -1 | -5 | -25 | -89 | -277 | -445 | -521 | -1,385 | -2,225 | -2,605 | -6,925 | -13,025 | -24,653 | -46,369 | -123,265 | -144,317 | -231,845 | -616,325 | -721,585 | -1,159,225 | -3,607,925 | -12,844,213 | -64,221,065 | -321,105,325 |
