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 222,342,127, 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 | 222,342,127 | |
| -1 | -222,342,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,342,127.
Example:
1 x 222,342,127 = 222,342,127
and
-1 x -222,342,127 = 222,342,127
Notice both answers equal 222,342,127
With that explanation out of the way, let's continue. Next, we take the number 222,342,127 and divide it by 2:
222,342,127 ÷ 2 = 111,171,063.5
If the quotient is a whole number, then 2 and 111,171,063.5 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 | 222,342,127 | |
| -1 | -222,342,127 |
Now, we try dividing 222,342,127 by 3:
222,342,127 ÷ 3 = 74,114,042.3333
If the quotient is a whole number, then 3 and 74,114,042.3333 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 | 222,342,127 | |
| -1 | -222,342,127 |
Let's try dividing by 4:
222,342,127 ÷ 4 = 55,585,531.75
If the quotient is a whole number, then 4 and 55,585,531.75 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 | 222,342,127 | |
| -1 | 222,342,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 853 | 1,619 | 5,971 | 11,333 | 19,619 | 37,237 | 137,333 | 260,659 | 1,381,007 | 9,667,049 | 31,763,161 | 222,342,127 |
| -1 | -7 | -23 | -161 | -853 | -1,619 | -5,971 | -11,333 | -19,619 | -37,237 | -137,333 | -260,659 | -1,381,007 | -9,667,049 | -31,763,161 | -222,342,127 |
