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 222,303,323, 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 | 222,303,323 | |
| -1 | -222,303,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,303,323.
Example:
1 x 222,303,323 = 222,303,323
and
-1 x -222,303,323 = 222,303,323
Notice both answers equal 222,303,323
With that explanation out of the way, let's continue. Next, we take the number 222,303,323 and divide it by 2:
222,303,323 ÷ 2 = 111,151,661.5
If the quotient is a whole number, then 2 and 111,151,661.5 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 | 222,303,323 | |
| -1 | -222,303,323 |
Now, we try dividing 222,303,323 by 3:
222,303,323 ÷ 3 = 74,101,107.6667
If the quotient is a whole number, then 3 and 74,101,107.6667 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 | 222,303,323 | |
| -1 | -222,303,323 |
Let's try dividing by 4:
222,303,323 ÷ 4 = 55,575,830.75
If the quotient is a whole number, then 4 and 55,575,830.75 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 | 222,303,323 | |
| -1 | 222,303,323 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 101 | 803 | 1,111 | 2,741 | 7,373 | 30,151 | 81,103 | 200,093 | 276,841 | 2,201,023 | 3,045,251 | 20,209,393 | 222,303,323 |
| -1 | -11 | -73 | -101 | -803 | -1,111 | -2,741 | -7,373 | -30,151 | -81,103 | -200,093 | -276,841 | -2,201,023 | -3,045,251 | -20,209,393 | -222,303,323 |
