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 200,230,121, 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 | 200,230,121 | |
| -1 | -200,230,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,230,121.
Example:
1 x 200,230,121 = 200,230,121
and
-1 x -200,230,121 = 200,230,121
Notice both answers equal 200,230,121
With that explanation out of the way, let's continue. Next, we take the number 200,230,121 and divide it by 2:
200,230,121 ÷ 2 = 100,115,060.5
If the quotient is a whole number, then 2 and 100,115,060.5 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 | 200,230,121 | |
| -1 | -200,230,121 |
Now, we try dividing 200,230,121 by 3:
200,230,121 ÷ 3 = 66,743,373.6667
If the quotient is a whole number, then 3 and 66,743,373.6667 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 | 200,230,121 | |
| -1 | -200,230,121 |
Let's try dividing by 4:
200,230,121 ÷ 4 = 50,057,530.25
If the quotient is a whole number, then 4 and 50,057,530.25 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 | 200,230,121 | |
| -1 | 200,230,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 61 | 91 | 427 | 637 | 793 | 2,989 | 5,153 | 5,551 | 36,071 | 38,857 | 66,989 | 252,497 | 314,333 | 468,923 | 2,200,331 | 3,282,461 | 4,086,329 | 15,402,317 | 28,604,303 | 200,230,121 |
| -1 | -7 | -13 | -49 | -61 | -91 | -427 | -637 | -793 | -2,989 | -5,153 | -5,551 | -36,071 | -38,857 | -66,989 | -252,497 | -314,333 | -468,923 | -2,200,331 | -3,282,461 | -4,086,329 | -15,402,317 | -28,604,303 | -200,230,121 |
