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 220,010,231, 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 | 220,010,231 | |
| -1 | -220,010,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,010,231.
Example:
1 x 220,010,231 = 220,010,231
and
-1 x -220,010,231 = 220,010,231
Notice both answers equal 220,010,231
With that explanation out of the way, let's continue. Next, we take the number 220,010,231 and divide it by 2:
220,010,231 ÷ 2 = 110,005,115.5
If the quotient is a whole number, then 2 and 110,005,115.5 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 | 220,010,231 | |
| -1 | -220,010,231 |
Now, we try dividing 220,010,231 by 3:
220,010,231 ÷ 3 = 73,336,743.6667
If the quotient is a whole number, then 3 and 73,336,743.6667 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 | 220,010,231 | |
| -1 | -220,010,231 |
Let's try dividing by 4:
220,010,231 ÷ 4 = 55,002,557.75
If the quotient is a whole number, then 4 and 55,002,557.75 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 | 220,010,231 | |
| -1 | 220,010,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 389 | 1,879 | 2,723 | 13,153 | 16,727 | 80,797 | 117,089 | 565,579 | 730,931 | 5,116,517 | 31,430,033 | 220,010,231 |
| -1 | -7 | -43 | -301 | -389 | -1,879 | -2,723 | -13,153 | -16,727 | -80,797 | -117,089 | -565,579 | -730,931 | -5,116,517 | -31,430,033 | -220,010,231 |
