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 326,850,353, 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 | 326,850,353 | |
| -1 | -326,850,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,850,353.
Example:
1 x 326,850,353 = 326,850,353
and
-1 x -326,850,353 = 326,850,353
Notice both answers equal 326,850,353
With that explanation out of the way, let's continue. Next, we take the number 326,850,353 and divide it by 2:
326,850,353 ÷ 2 = 163,425,176.5
If the quotient is a whole number, then 2 and 163,425,176.5 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 | 326,850,353 | |
| -1 | -326,850,353 |
Now, we try dividing 326,850,353 by 3:
326,850,353 ÷ 3 = 108,950,117.6667
If the quotient is a whole number, then 3 and 108,950,117.6667 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 | 326,850,353 | |
| -1 | -326,850,353 |
Let's try dividing by 4:
326,850,353 ÷ 4 = 81,712,588.25
If the quotient is a whole number, then 4 and 81,712,588.25 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 | 326,850,353 | |
| -1 | 326,850,353 |
If you did it right, you will end up with this table:
| 1 | 43 | 113 | 137 | 491 | 4,859 | 5,891 | 15,481 | 21,113 | 55,483 | 67,267 | 665,683 | 2,385,769 | 2,892,481 | 7,601,171 | 326,850,353 |
| -1 | -43 | -113 | -137 | -491 | -4,859 | -5,891 | -15,481 | -21,113 | -55,483 | -67,267 | -665,683 | -2,385,769 | -2,892,481 | -7,601,171 | -326,850,353 |
