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 222,450,355, 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 | 222,450,355 | |
| -1 | -222,450,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,450,355.
Example:
1 x 222,450,355 = 222,450,355
and
-1 x -222,450,355 = 222,450,355
Notice both answers equal 222,450,355
With that explanation out of the way, let's continue. Next, we take the number 222,450,355 and divide it by 2:
222,450,355 ÷ 2 = 111,225,177.5
If the quotient is a whole number, then 2 and 111,225,177.5 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 | 222,450,355 | |
| -1 | -222,450,355 |
Now, we try dividing 222,450,355 by 3:
222,450,355 ÷ 3 = 74,150,118.3333
If the quotient is a whole number, then 3 and 74,150,118.3333 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 | 222,450,355 | |
| -1 | -222,450,355 |
Let's try dividing by 4:
222,450,355 ÷ 4 = 55,612,588.75
If the quotient is a whole number, then 4 and 55,612,588.75 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 | 222,450,355 | |
| -1 | 222,450,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 59 | 85 | 295 | 1,003 | 5,015 | 44,357 | 221,785 | 754,069 | 2,617,063 | 3,770,345 | 13,085,315 | 44,490,071 | 222,450,355 |
| -1 | -5 | -17 | -59 | -85 | -295 | -1,003 | -5,015 | -44,357 | -221,785 | -754,069 | -2,617,063 | -3,770,345 | -13,085,315 | -44,490,071 | -222,450,355 |
