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 326,588,003, 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 | 326,588,003 | |
| -1 | -326,588,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,588,003.
Example:
1 x 326,588,003 = 326,588,003
and
-1 x -326,588,003 = 326,588,003
Notice both answers equal 326,588,003
With that explanation out of the way, let's continue. Next, we take the number 326,588,003 and divide it by 2:
326,588,003 ÷ 2 = 163,294,001.5
If the quotient is a whole number, then 2 and 163,294,001.5 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 | 326,588,003 | |
| -1 | -326,588,003 |
Now, we try dividing 326,588,003 by 3:
326,588,003 ÷ 3 = 108,862,667.6667
If the quotient is a whole number, then 3 and 108,862,667.6667 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 | 326,588,003 | |
| -1 | -326,588,003 |
Let's try dividing by 4:
326,588,003 ÷ 4 = 81,647,000.75
If the quotient is a whole number, then 4 and 81,647,000.75 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 | 326,588,003 | |
| -1 | 326,588,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 239 | 1,673 | 4,063 | 11,483 | 28,441 | 80,381 | 195,211 | 1,366,477 | 2,744,437 | 19,211,059 | 46,655,429 | 326,588,003 |
| -1 | -7 | -17 | -119 | -239 | -1,673 | -4,063 | -11,483 | -28,441 | -80,381 | -195,211 | -1,366,477 | -2,744,437 | -19,211,059 | -46,655,429 | -326,588,003 |
