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 222,006,317, 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 | 222,006,317 | |
| -1 | -222,006,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,006,317.
Example:
1 x 222,006,317 = 222,006,317
and
-1 x -222,006,317 = 222,006,317
Notice both answers equal 222,006,317
With that explanation out of the way, let's continue. Next, we take the number 222,006,317 and divide it by 2:
222,006,317 ÷ 2 = 111,003,158.5
If the quotient is a whole number, then 2 and 111,003,158.5 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 | 222,006,317 | |
| -1 | -222,006,317 |
Now, we try dividing 222,006,317 by 3:
222,006,317 ÷ 3 = 74,002,105.6667
If the quotient is a whole number, then 3 and 74,002,105.6667 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 | 222,006,317 | |
| -1 | -222,006,317 |
Let's try dividing by 4:
222,006,317 ÷ 4 = 55,501,579.25
If the quotient is a whole number, then 4 and 55,501,579.25 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 | 222,006,317 | |
| -1 | 222,006,317 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 89 | 247 | 1,157 | 1,691 | 10,099 | 21,983 | 131,287 | 191,881 | 898,811 | 2,494,453 | 11,684,543 | 17,077,409 | 222,006,317 |
| -1 | -13 | -19 | -89 | -247 | -1,157 | -1,691 | -10,099 | -21,983 | -131,287 | -191,881 | -898,811 | -2,494,453 | -11,684,543 | -17,077,409 | -222,006,317 |
