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 328,425,685, 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 | 328,425,685 | |
| -1 | -328,425,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 328,425,685.
Example:
1 x 328,425,685 = 328,425,685
and
-1 x -328,425,685 = 328,425,685
Notice both answers equal 328,425,685
With that explanation out of the way, let's continue. Next, we take the number 328,425,685 and divide it by 2:
328,425,685 ÷ 2 = 164,212,842.5
If the quotient is a whole number, then 2 and 164,212,842.5 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 | 328,425,685 | |
| -1 | -328,425,685 |
Now, we try dividing 328,425,685 by 3:
328,425,685 ÷ 3 = 109,475,228.3333
If the quotient is a whole number, then 3 and 109,475,228.3333 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 | 328,425,685 | |
| -1 | -328,425,685 |
Let's try dividing by 4:
328,425,685 ÷ 4 = 82,106,421.25
If the quotient is a whole number, then 4 and 82,106,421.25 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 | 328,425,685 | |
| -1 | 328,425,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 809 | 1,657 | 4,045 | 5,663 | 8,285 | 11,599 | 28,315 | 39,641 | 57,995 | 81,193 | 198,205 | 405,965 | 1,340,513 | 6,702,565 | 9,383,591 | 46,917,955 | 65,685,137 | 328,425,685 |
| -1 | -5 | -7 | -35 | -49 | -245 | -809 | -1,657 | -4,045 | -5,663 | -8,285 | -11,599 | -28,315 | -39,641 | -57,995 | -81,193 | -198,205 | -405,965 | -1,340,513 | -6,702,565 | -9,383,591 | -46,917,955 | -65,685,137 | -328,425,685 |
