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 326,677,307, 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 | 326,677,307 | |
| -1 | -326,677,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,677,307.
Example:
1 x 326,677,307 = 326,677,307
and
-1 x -326,677,307 = 326,677,307
Notice both answers equal 326,677,307
With that explanation out of the way, let's continue. Next, we take the number 326,677,307 and divide it by 2:
326,677,307 ÷ 2 = 163,338,653.5
If the quotient is a whole number, then 2 and 163,338,653.5 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 | 326,677,307 | |
| -1 | -326,677,307 |
Now, we try dividing 326,677,307 by 3:
326,677,307 ÷ 3 = 108,892,435.6667
If the quotient is a whole number, then 3 and 108,892,435.6667 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 | 326,677,307 | |
| -1 | -326,677,307 |
Let's try dividing by 4:
326,677,307 ÷ 4 = 81,669,326.75
If the quotient is a whole number, then 4 and 81,669,326.75 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 | 326,677,307 | |
| -1 | 326,677,307 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 181 | 517 | 1,991 | 3,491 | 8,507 | 38,401 | 93,577 | 164,077 | 631,871 | 1,804,847 | 6,950,581 | 29,697,937 | 326,677,307 |
| -1 | -11 | -47 | -181 | -517 | -1,991 | -3,491 | -8,507 | -38,401 | -93,577 | -164,077 | -631,871 | -1,804,847 | -6,950,581 | -29,697,937 | -326,677,307 |
