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 325,243,345, 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 | 325,243,345 | |
| -1 | -325,243,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 325,243,345.
Example:
1 x 325,243,345 = 325,243,345
and
-1 x -325,243,345 = 325,243,345
Notice both answers equal 325,243,345
With that explanation out of the way, let's continue. Next, we take the number 325,243,345 and divide it by 2:
325,243,345 ÷ 2 = 162,621,672.5
If the quotient is a whole number, then 2 and 162,621,672.5 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 | 325,243,345 | |
| -1 | -325,243,345 |
Now, we try dividing 325,243,345 by 3:
325,243,345 ÷ 3 = 108,414,448.3333
If the quotient is a whole number, then 3 and 108,414,448.3333 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 | 325,243,345 | |
| -1 | -325,243,345 |
Let's try dividing by 4:
325,243,345 ÷ 4 = 81,310,836.25
If the quotient is a whole number, then 4 and 81,310,836.25 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 | 325,243,345 | |
| -1 | 325,243,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 404,029 | 2,020,145 | 2,828,203 | 9,292,667 | 14,141,015 | 46,463,335 | 65,048,669 | 325,243,345 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -404,029 | -2,020,145 | -2,828,203 | -9,292,667 | -14,141,015 | -46,463,335 | -65,048,669 | -325,243,345 |
