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 222,214,735, 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 | 222,214,735 | |
| -1 | -222,214,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,214,735.
Example:
1 x 222,214,735 = 222,214,735
and
-1 x -222,214,735 = 222,214,735
Notice both answers equal 222,214,735
With that explanation out of the way, let's continue. Next, we take the number 222,214,735 and divide it by 2:
222,214,735 ÷ 2 = 111,107,367.5
If the quotient is a whole number, then 2 and 111,107,367.5 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 | 222,214,735 | |
| -1 | -222,214,735 |
Now, we try dividing 222,214,735 by 3:
222,214,735 ÷ 3 = 74,071,578.3333
If the quotient is a whole number, then 3 and 74,071,578.3333 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 | 222,214,735 | |
| -1 | -222,214,735 |
Let's try dividing by 4:
222,214,735 ÷ 4 = 55,553,683.75
If the quotient is a whole number, then 4 and 55,553,683.75 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 | 222,214,735 | |
| -1 | 222,214,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 355 | 1,207 | 6,035 | 36,821 | 184,105 | 625,957 | 2,614,291 | 3,129,785 | 13,071,455 | 44,442,947 | 222,214,735 |
| -1 | -5 | -17 | -71 | -85 | -355 | -1,207 | -6,035 | -36,821 | -184,105 | -625,957 | -2,614,291 | -3,129,785 | -13,071,455 | -44,442,947 | -222,214,735 |
