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 202,014,455, 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 | 202,014,455 | |
| -1 | -202,014,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,014,455.
Example:
1 x 202,014,455 = 202,014,455
and
-1 x -202,014,455 = 202,014,455
Notice both answers equal 202,014,455
With that explanation out of the way, let's continue. Next, we take the number 202,014,455 and divide it by 2:
202,014,455 ÷ 2 = 101,007,227.5
If the quotient is a whole number, then 2 and 101,007,227.5 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 | 202,014,455 | |
| -1 | -202,014,455 |
Now, we try dividing 202,014,455 by 3:
202,014,455 ÷ 3 = 67,338,151.6667
If the quotient is a whole number, then 3 and 67,338,151.6667 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 | 202,014,455 | |
| -1 | -202,014,455 |
Let's try dividing by 4:
202,014,455 ÷ 4 = 50,503,613.75
If the quotient is a whole number, then 4 and 50,503,613.75 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 | 202,014,455 | |
| -1 | 202,014,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 127 | 395 | 635 | 4,027 | 10,033 | 20,135 | 50,165 | 318,133 | 511,429 | 1,590,665 | 2,557,145 | 40,402,891 | 202,014,455 |
| -1 | -5 | -79 | -127 | -395 | -635 | -4,027 | -10,033 | -20,135 | -50,165 | -318,133 | -511,429 | -1,590,665 | -2,557,145 | -40,402,891 | -202,014,455 |
