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 222,122,219, 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 | 222,122,219 | |
| -1 | -222,122,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,122,219.
Example:
1 x 222,122,219 = 222,122,219
and
-1 x -222,122,219 = 222,122,219
Notice both answers equal 222,122,219
With that explanation out of the way, let's continue. Next, we take the number 222,122,219 and divide it by 2:
222,122,219 ÷ 2 = 111,061,109.5
If the quotient is a whole number, then 2 and 111,061,109.5 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 | 222,122,219 | |
| -1 | -222,122,219 |
Now, we try dividing 222,122,219 by 3:
222,122,219 ÷ 3 = 74,040,739.6667
If the quotient is a whole number, then 3 and 74,040,739.6667 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 | 222,122,219 | |
| -1 | -222,122,219 |
Let's try dividing by 4:
222,122,219 ÷ 4 = 55,530,554.75
If the quotient is a whole number, then 4 and 55,530,554.75 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 | 222,122,219 | |
| -1 | 222,122,219 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 67 | 163 | 473 | 737 | 1,793 | 1,849 | 2,881 | 7,009 | 10,921 | 20,339 | 31,691 | 77,099 | 120,131 | 123,883 | 301,387 | 469,603 | 1,362,713 | 3,315,257 | 5,165,633 | 20,192,929 | 222,122,219 |
| -1 | -11 | -43 | -67 | -163 | -473 | -737 | -1,793 | -1,849 | -2,881 | -7,009 | -10,921 | -20,339 | -31,691 | -77,099 | -120,131 | -123,883 | -301,387 | -469,603 | -1,362,713 | -3,315,257 | -5,165,633 | -20,192,929 | -222,122,219 |
