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 200,211,107, 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 | 200,211,107 | |
| -1 | -200,211,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,211,107.
Example:
1 x 200,211,107 = 200,211,107
and
-1 x -200,211,107 = 200,211,107
Notice both answers equal 200,211,107
With that explanation out of the way, let's continue. Next, we take the number 200,211,107 and divide it by 2:
200,211,107 ÷ 2 = 100,105,553.5
If the quotient is a whole number, then 2 and 100,105,553.5 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 | 200,211,107 | |
| -1 | -200,211,107 |
Now, we try dividing 200,211,107 by 3:
200,211,107 ÷ 3 = 66,737,035.6667
If the quotient is a whole number, then 3 and 66,737,035.6667 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 | 200,211,107 | |
| -1 | -200,211,107 |
Let's try dividing by 4:
200,211,107 ÷ 4 = 50,052,776.75
If the quotient is a whole number, then 4 and 50,052,776.75 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 | 200,211,107 | |
| -1 | 200,211,107 |
If you did it right, you will end up with this table:
| 1 | 37 | 89 | 163 | 373 | 3,293 | 6,031 | 13,801 | 14,507 | 33,197 | 60,799 | 536,759 | 1,228,289 | 2,249,563 | 5,411,111 | 200,211,107 |
| -1 | -37 | -89 | -163 | -373 | -3,293 | -6,031 | -13,801 | -14,507 | -33,197 | -60,799 | -536,759 | -1,228,289 | -2,249,563 | -5,411,111 | -200,211,107 |
