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 200,010,239, 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 | 200,010,239 | |
| -1 | -200,010,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,010,239.
Example:
1 x 200,010,239 = 200,010,239
and
-1 x -200,010,239 = 200,010,239
Notice both answers equal 200,010,239
With that explanation out of the way, let's continue. Next, we take the number 200,010,239 and divide it by 2:
200,010,239 ÷ 2 = 100,005,119.5
If the quotient is a whole number, then 2 and 100,005,119.5 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 | 200,010,239 | |
| -1 | -200,010,239 |
Now, we try dividing 200,010,239 by 3:
200,010,239 ÷ 3 = 66,670,079.6667
If the quotient is a whole number, then 3 and 66,670,079.6667 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 | 200,010,239 | |
| -1 | -200,010,239 |
Let's try dividing by 4:
200,010,239 ÷ 4 = 50,002,559.75
If the quotient is a whole number, then 4 and 50,002,559.75 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 | 200,010,239 | |
| -1 | 200,010,239 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 47 | 143 | 517 | 611 | 6,721 | 29,759 | 327,349 | 386,867 | 1,398,673 | 4,255,537 | 15,385,403 | 18,182,749 | 200,010,239 |
| -1 | -11 | -13 | -47 | -143 | -517 | -611 | -6,721 | -29,759 | -327,349 | -386,867 | -1,398,673 | -4,255,537 | -15,385,403 | -18,182,749 | -200,010,239 |
