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 202,310,231, 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 | 202,310,231 | |
| -1 | -202,310,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,310,231.
Example:
1 x 202,310,231 = 202,310,231
and
-1 x -202,310,231 = 202,310,231
Notice both answers equal 202,310,231
With that explanation out of the way, let's continue. Next, we take the number 202,310,231 and divide it by 2:
202,310,231 ÷ 2 = 101,155,115.5
If the quotient is a whole number, then 2 and 101,155,115.5 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 | 202,310,231 | |
| -1 | -202,310,231 |
Now, we try dividing 202,310,231 by 3:
202,310,231 ÷ 3 = 67,436,743.6667
If the quotient is a whole number, then 3 and 67,436,743.6667 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 | 202,310,231 | |
| -1 | -202,310,231 |
Let's try dividing by 4:
202,310,231 ÷ 4 = 50,577,557.75
If the quotient is a whole number, then 4 and 50,577,557.75 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 | 202,310,231 | |
| -1 | 202,310,231 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 79 | 103 | 529 | 1,081 | 1,817 | 2,369 | 3,713 | 4,841 | 8,137 | 24,863 | 41,791 | 54,487 | 85,399 | 111,343 | 187,151 | 382,439 | 1,964,177 | 2,560,889 | 4,304,473 | 8,796,097 | 202,310,231 |
| -1 | -23 | -47 | -79 | -103 | -529 | -1,081 | -1,817 | -2,369 | -3,713 | -4,841 | -8,137 | -24,863 | -41,791 | -54,487 | -85,399 | -111,343 | -187,151 | -382,439 | -1,964,177 | -2,560,889 | -4,304,473 | -8,796,097 | -202,310,231 |
