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 222,003,199, 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 | 222,003,199 | |
| -1 | -222,003,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,003,199.
Example:
1 x 222,003,199 = 222,003,199
and
-1 x -222,003,199 = 222,003,199
Notice both answers equal 222,003,199
With that explanation out of the way, let's continue. Next, we take the number 222,003,199 and divide it by 2:
222,003,199 ÷ 2 = 111,001,599.5
If the quotient is a whole number, then 2 and 111,001,599.5 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 | 222,003,199 | |
| -1 | -222,003,199 |
Now, we try dividing 222,003,199 by 3:
222,003,199 ÷ 3 = 74,001,066.3333
If the quotient is a whole number, then 3 and 74,001,066.3333 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 | 222,003,199 | |
| -1 | -222,003,199 |
Let's try dividing by 4:
222,003,199 ÷ 4 = 55,500,799.75
If the quotient is a whole number, then 4 and 55,500,799.75 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 | 222,003,199 | |
| -1 | 222,003,199 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 743 | 1,181 | 8,173 | 12,991 | 17,089 | 27,163 | 187,979 | 298,793 | 877,483 | 9,652,313 | 20,182,109 | 222,003,199 |
| -1 | -11 | -23 | -253 | -743 | -1,181 | -8,173 | -12,991 | -17,089 | -27,163 | -187,979 | -298,793 | -877,483 | -9,652,313 | -20,182,109 | -222,003,199 |
