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 200,011,105, 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 | 200,011,105 | |
| -1 | -200,011,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,011,105.
Example:
1 x 200,011,105 = 200,011,105
and
-1 x -200,011,105 = 200,011,105
Notice both answers equal 200,011,105
With that explanation out of the way, let's continue. Next, we take the number 200,011,105 and divide it by 2:
200,011,105 ÷ 2 = 100,005,552.5
If the quotient is a whole number, then 2 and 100,005,552.5 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 | 200,011,105 | |
| -1 | -200,011,105 |
Now, we try dividing 200,011,105 by 3:
200,011,105 ÷ 3 = 66,670,368.3333
If the quotient is a whole number, then 3 and 66,670,368.3333 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 | 200,011,105 | |
| -1 | -200,011,105 |
Let's try dividing by 4:
200,011,105 ÷ 4 = 50,002,776.25
If the quotient is a whole number, then 4 and 50,002,776.25 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 | 200,011,105 | |
| -1 | 200,011,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 248,461 | 1,242,305 | 1,739,227 | 5,714,603 | 8,696,135 | 28,573,015 | 40,002,221 | 200,011,105 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -248,461 | -1,242,305 | -1,739,227 | -5,714,603 | -8,696,135 | -28,573,015 | -40,002,221 | -200,011,105 |
