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 222,003,119, 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 | 222,003,119 | |
| -1 | -222,003,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,003,119.
Example:
1 x 222,003,119 = 222,003,119
and
-1 x -222,003,119 = 222,003,119
Notice both answers equal 222,003,119
With that explanation out of the way, let's continue. Next, we take the number 222,003,119 and divide it by 2:
222,003,119 ÷ 2 = 111,001,559.5
If the quotient is a whole number, then 2 and 111,001,559.5 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 | 222,003,119 | |
| -1 | -222,003,119 |
Now, we try dividing 222,003,119 by 3:
222,003,119 ÷ 3 = 74,001,039.6667
If the quotient is a whole number, then 3 and 74,001,039.6667 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 | 222,003,119 | |
| -1 | -222,003,119 |
Let's try dividing by 4:
222,003,119 ÷ 4 = 55,500,779.75
If the quotient is a whole number, then 4 and 55,500,779.75 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 | 222,003,119 | |
| -1 | 222,003,119 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 757 | 1,327 | 9,841 | 12,869 | 17,251 | 22,559 | 167,297 | 293,267 | 1,004,539 | 13,059,007 | 17,077,163 | 222,003,119 |
| -1 | -13 | -17 | -221 | -757 | -1,327 | -9,841 | -12,869 | -17,251 | -22,559 | -167,297 | -293,267 | -1,004,539 | -13,059,007 | -17,077,163 | -222,003,119 |
