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 222,040,441, 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 | 222,040,441 | |
| -1 | -222,040,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,040,441.
Example:
1 x 222,040,441 = 222,040,441
and
-1 x -222,040,441 = 222,040,441
Notice both answers equal 222,040,441
With that explanation out of the way, let's continue. Next, we take the number 222,040,441 and divide it by 2:
222,040,441 ÷ 2 = 111,020,220.5
If the quotient is a whole number, then 2 and 111,020,220.5 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 | 222,040,441 | |
| -1 | -222,040,441 |
Now, we try dividing 222,040,441 by 3:
222,040,441 ÷ 3 = 74,013,480.3333
If the quotient is a whole number, then 3 and 74,013,480.3333 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 | 222,040,441 | |
| -1 | -222,040,441 |
Let's try dividing by 4:
222,040,441 ÷ 4 = 55,510,110.25
If the quotient is a whole number, then 4 and 55,510,110.25 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 | 222,040,441 | |
| -1 | 222,040,441 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 4,921 | 45,121 | 315,847 | 857,299 | 1,669,477 | 6,001,093 | 11,686,339 | 31,720,063 | 222,040,441 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -4,921 | -45,121 | -315,847 | -857,299 | -1,669,477 | -6,001,093 | -11,686,339 | -31,720,063 | -222,040,441 |
