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 222,401,311, 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 | 222,401,311 | |
| -1 | -222,401,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,401,311.
Example:
1 x 222,401,311 = 222,401,311
and
-1 x -222,401,311 = 222,401,311
Notice both answers equal 222,401,311
With that explanation out of the way, let's continue. Next, we take the number 222,401,311 and divide it by 2:
222,401,311 ÷ 2 = 111,200,655.5
If the quotient is a whole number, then 2 and 111,200,655.5 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 | 222,401,311 | |
| -1 | -222,401,311 |
Now, we try dividing 222,401,311 by 3:
222,401,311 ÷ 3 = 74,133,770.3333
If the quotient is a whole number, then 3 and 74,133,770.3333 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 | 222,401,311 | |
| -1 | -222,401,311 |
Let's try dividing by 4:
222,401,311 ÷ 4 = 55,600,327.75
If the quotient is a whole number, then 4 and 55,600,327.75 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 | 222,401,311 | |
| -1 | 222,401,311 |
If you did it right, you will end up with this table:
| 1 | 11 | 109 | 251 | 739 | 1,199 | 2,761 | 8,129 | 27,359 | 80,551 | 185,489 | 300,949 | 886,061 | 2,040,379 | 20,218,301 | 222,401,311 |
| -1 | -11 | -109 | -251 | -739 | -1,199 | -2,761 | -8,129 | -27,359 | -80,551 | -185,489 | -300,949 | -886,061 | -2,040,379 | -20,218,301 | -222,401,311 |
