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 222,535,355, 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 | 222,535,355 | |
| -1 | -222,535,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,535,355.
Example:
1 x 222,535,355 = 222,535,355
and
-1 x -222,535,355 = 222,535,355
Notice both answers equal 222,535,355
With that explanation out of the way, let's continue. Next, we take the number 222,535,355 and divide it by 2:
222,535,355 ÷ 2 = 111,267,677.5
If the quotient is a whole number, then 2 and 111,267,677.5 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 | 222,535,355 | |
| -1 | -222,535,355 |
Now, we try dividing 222,535,355 by 3:
222,535,355 ÷ 3 = 74,178,451.6667
If the quotient is a whole number, then 3 and 74,178,451.6667 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 | 222,535,355 | |
| -1 | -222,535,355 |
Let's try dividing by 4:
222,535,355 ÷ 4 = 55,633,838.75
If the quotient is a whole number, then 4 and 55,633,838.75 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 | 222,535,355 | |
| -1 | 222,535,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 374,009 | 1,870,045 | 2,618,063 | 6,358,153 | 13,090,315 | 31,790,765 | 44,507,071 | 222,535,355 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -374,009 | -1,870,045 | -2,618,063 | -6,358,153 | -13,090,315 | -31,790,765 | -44,507,071 | -222,535,355 |
