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 200,201,023, 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 | 200,201,023 | |
| -1 | -200,201,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,201,023.
Example:
1 x 200,201,023 = 200,201,023
and
-1 x -200,201,023 = 200,201,023
Notice both answers equal 200,201,023
With that explanation out of the way, let's continue. Next, we take the number 200,201,023 and divide it by 2:
200,201,023 ÷ 2 = 100,100,511.5
If the quotient is a whole number, then 2 and 100,100,511.5 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 | 200,201,023 | |
| -1 | -200,201,023 |
Now, we try dividing 200,201,023 by 3:
200,201,023 ÷ 3 = 66,733,674.3333
If the quotient is a whole number, then 3 and 66,733,674.3333 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 | 200,201,023 | |
| -1 | -200,201,023 |
Let's try dividing by 4:
200,201,023 ÷ 4 = 50,050,255.75
If the quotient is a whole number, then 4 and 50,050,255.75 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 | 200,201,023 | |
| -1 | 200,201,023 |
If you did it right, you will end up with this table:
| 1 | 11 | 181 | 193 | 521 | 1,991 | 2,123 | 5,731 | 34,933 | 94,301 | 100,553 | 384,263 | 1,037,311 | 1,106,083 | 18,200,093 | 200,201,023 |
| -1 | -11 | -181 | -193 | -521 | -1,991 | -2,123 | -5,731 | -34,933 | -94,301 | -100,553 | -384,263 | -1,037,311 | -1,106,083 | -18,200,093 | -200,201,023 |
