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 222,331,333, 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 | 222,331,333 | |
| -1 | -222,331,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,331,333.
Example:
1 x 222,331,333 = 222,331,333
and
-1 x -222,331,333 = 222,331,333
Notice both answers equal 222,331,333
With that explanation out of the way, let's continue. Next, we take the number 222,331,333 and divide it by 2:
222,331,333 ÷ 2 = 111,165,666.5
If the quotient is a whole number, then 2 and 111,165,666.5 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 | 222,331,333 | |
| -1 | -222,331,333 |
Now, we try dividing 222,331,333 by 3:
222,331,333 ÷ 3 = 74,110,444.3333
If the quotient is a whole number, then 3 and 74,110,444.3333 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 | 222,331,333 | |
| -1 | -222,331,333 |
Let's try dividing by 4:
222,331,333 ÷ 4 = 55,582,833.25
If the quotient is a whole number, then 4 and 55,582,833.25 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 | 222,331,333 | |
| -1 | 222,331,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 211 | 763 | 1,381 | 1,477 | 9,667 | 22,999 | 150,529 | 160,993 | 291,391 | 1,053,703 | 2,039,737 | 31,761,619 | 222,331,333 |
| -1 | -7 | -109 | -211 | -763 | -1,381 | -1,477 | -9,667 | -22,999 | -150,529 | -160,993 | -291,391 | -1,053,703 | -2,039,737 | -31,761,619 | -222,331,333 |
