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 222,331,031, 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 | 222,331,031 | |
| -1 | -222,331,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,331,031.
Example:
1 x 222,331,031 = 222,331,031
and
-1 x -222,331,031 = 222,331,031
Notice both answers equal 222,331,031
With that explanation out of the way, let's continue. Next, we take the number 222,331,031 and divide it by 2:
222,331,031 ÷ 2 = 111,165,515.5
If the quotient is a whole number, then 2 and 111,165,515.5 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 | 222,331,031 | |
| -1 | -222,331,031 |
Now, we try dividing 222,331,031 by 3:
222,331,031 ÷ 3 = 74,110,343.6667
If the quotient is a whole number, then 3 and 74,110,343.6667 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 | 222,331,031 | |
| -1 | -222,331,031 |
Let's try dividing by 4:
222,331,031 ÷ 4 = 55,582,757.75
If the quotient is a whole number, then 4 and 55,582,757.75 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 | 222,331,031 | |
| -1 | 222,331,031 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 251 | 793 | 1,117 | 3,263 | 14,521 | 15,311 | 68,137 | 199,043 | 280,367 | 885,781 | 3,644,771 | 17,102,387 | 222,331,031 |
| -1 | -13 | -61 | -251 | -793 | -1,117 | -3,263 | -14,521 | -15,311 | -68,137 | -199,043 | -280,367 | -885,781 | -3,644,771 | -17,102,387 | -222,331,031 |
