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 325,110,331, 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 | 325,110,331 | |
| -1 | -325,110,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 325,110,331.
Example:
1 x 325,110,331 = 325,110,331
and
-1 x -325,110,331 = 325,110,331
Notice both answers equal 325,110,331
With that explanation out of the way, let's continue. Next, we take the number 325,110,331 and divide it by 2:
325,110,331 ÷ 2 = 162,555,165.5
If the quotient is a whole number, then 2 and 162,555,165.5 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 | 325,110,331 | |
| -1 | -325,110,331 |
Now, we try dividing 325,110,331 by 3:
325,110,331 ÷ 3 = 108,370,110.3333
If the quotient is a whole number, then 3 and 108,370,110.3333 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 | 325,110,331 | |
| -1 | -325,110,331 |
Let's try dividing by 4:
325,110,331 ÷ 4 = 81,277,582.75
If the quotient is a whole number, then 4 and 81,277,582.75 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 | 325,110,331 | |
| -1 | 325,110,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 67 | 91 | 469 | 871 | 6,097 | 53,323 | 373,261 | 693,199 | 3,572,641 | 4,852,393 | 25,008,487 | 46,444,333 | 325,110,331 |
| -1 | -7 | -13 | -67 | -91 | -469 | -871 | -6,097 | -53,323 | -373,261 | -693,199 | -3,572,641 | -4,852,393 | -25,008,487 | -46,444,333 | -325,110,331 |
