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 222,012,131, 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 | 222,012,131 | |
| -1 | -222,012,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,012,131.
Example:
1 x 222,012,131 = 222,012,131
and
-1 x -222,012,131 = 222,012,131
Notice both answers equal 222,012,131
With that explanation out of the way, let's continue. Next, we take the number 222,012,131 and divide it by 2:
222,012,131 ÷ 2 = 111,006,065.5
If the quotient is a whole number, then 2 and 111,006,065.5 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 | 222,012,131 | |
| -1 | -222,012,131 |
Now, we try dividing 222,012,131 by 3:
222,012,131 ÷ 3 = 74,004,043.6667
If the quotient is a whole number, then 3 and 74,004,043.6667 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 | 222,012,131 | |
| -1 | -222,012,131 |
Let's try dividing by 4:
222,012,131 ÷ 4 = 55,503,032.75
If the quotient is a whole number, then 4 and 55,503,032.75 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 | 222,012,131 | |
| -1 | 222,012,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 121 | 209 | 1,331 | 2,299 | 8,779 | 25,289 | 96,569 | 166,801 | 1,062,259 | 1,834,811 | 11,684,849 | 20,182,921 | 222,012,131 |
| -1 | -11 | -19 | -121 | -209 | -1,331 | -2,299 | -8,779 | -25,289 | -96,569 | -166,801 | -1,062,259 | -1,834,811 | -11,684,849 | -20,182,921 | -222,012,131 |
