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 208,882,003, 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 | 208,882,003 | |
| -1 | -208,882,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 208,882,003.
Example:
1 x 208,882,003 = 208,882,003
and
-1 x -208,882,003 = 208,882,003
Notice both answers equal 208,882,003
With that explanation out of the way, let's continue. Next, we take the number 208,882,003 and divide it by 2:
208,882,003 ÷ 2 = 104,441,001.5
If the quotient is a whole number, then 2 and 104,441,001.5 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 | 208,882,003 | |
| -1 | -208,882,003 |
Now, we try dividing 208,882,003 by 3:
208,882,003 ÷ 3 = 69,627,334.3333
If the quotient is a whole number, then 3 and 69,627,334.3333 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 | 208,882,003 | |
| -1 | -208,882,003 |
Let's try dividing by 4:
208,882,003 ÷ 4 = 52,220,500.75
If the quotient is a whole number, then 4 and 52,220,500.75 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 | 208,882,003 | |
| -1 | 208,882,003 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 43 | 451 | 473 | 1,763 | 10,771 | 19,393 | 118,481 | 441,611 | 463,153 | 4,857,721 | 5,094,683 | 18,989,273 | 208,882,003 |
| -1 | -11 | -41 | -43 | -451 | -473 | -1,763 | -10,771 | -19,393 | -118,481 | -441,611 | -463,153 | -4,857,721 | -5,094,683 | -18,989,273 | -208,882,003 |
