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 325,550,617, 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 | 325,550,617 | |
| -1 | -325,550,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 325,550,617.
Example:
1 x 325,550,617 = 325,550,617
and
-1 x -325,550,617 = 325,550,617
Notice both answers equal 325,550,617
With that explanation out of the way, let's continue. Next, we take the number 325,550,617 and divide it by 2:
325,550,617 ÷ 2 = 162,775,308.5
If the quotient is a whole number, then 2 and 162,775,308.5 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 | 325,550,617 | |
| -1 | -325,550,617 |
Now, we try dividing 325,550,617 by 3:
325,550,617 ÷ 3 = 108,516,872.3333
If the quotient is a whole number, then 3 and 108,516,872.3333 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 | 325,550,617 | |
| -1 | -325,550,617 |
Let's try dividing by 4:
325,550,617 ÷ 4 = 81,387,654.25
If the quotient is a whole number, then 4 and 81,387,654.25 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 | 325,550,617 | |
| -1 | 325,550,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 433 | 3,031 | 5,653 | 8,227 | 39,571 | 57,589 | 107,407 | 751,849 | 2,447,749 | 17,134,243 | 46,507,231 | 325,550,617 |
| -1 | -7 | -19 | -133 | -433 | -3,031 | -5,653 | -8,227 | -39,571 | -57,589 | -107,407 | -751,849 | -2,447,749 | -17,134,243 | -46,507,231 | -325,550,617 |
