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 82,808,003, 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 | 82,808,003 | |
| -1 | -82,808,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,808,003.
Example:
1 x 82,808,003 = 82,808,003
and
-1 x -82,808,003 = 82,808,003
Notice both answers equal 82,808,003
With that explanation out of the way, let's continue. Next, we take the number 82,808,003 and divide it by 2:
82,808,003 ÷ 2 = 41,404,001.5
If the quotient is a whole number, then 2 and 41,404,001.5 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 | 82,808,003 | |
| -1 | -82,808,003 |
Now, we try dividing 82,808,003 by 3:
82,808,003 ÷ 3 = 27,602,667.6667
If the quotient is a whole number, then 3 and 27,602,667.6667 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 | 82,808,003 | |
| -1 | -82,808,003 |
Let's try dividing by 4:
82,808,003 ÷ 4 = 20,702,000.75
If the quotient is a whole number, then 4 and 20,702,000.75 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 | 82,808,003 | |
| -1 | 82,808,003 |
If you did it right, you will end up with this table:
| 1 | 17 | 89 | 229 | 239 | 1,513 | 3,893 | 4,063 | 20,381 | 21,271 | 54,731 | 346,477 | 361,607 | 930,427 | 4,871,059 | 82,808,003 |
| -1 | -17 | -89 | -229 | -239 | -1,513 | -3,893 | -4,063 | -20,381 | -21,271 | -54,731 | -346,477 | -361,607 | -930,427 | -4,871,059 | -82,808,003 |
