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 228,161,065, 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 | 228,161,065 | |
| -1 | -228,161,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,161,065.
Example:
1 x 228,161,065 = 228,161,065
and
-1 x -228,161,065 = 228,161,065
Notice both answers equal 228,161,065
With that explanation out of the way, let's continue. Next, we take the number 228,161,065 and divide it by 2:
228,161,065 ÷ 2 = 114,080,532.5
If the quotient is a whole number, then 2 and 114,080,532.5 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 | 228,161,065 | |
| -1 | -228,161,065 |
Now, we try dividing 228,161,065 by 3:
228,161,065 ÷ 3 = 76,053,688.3333
If the quotient is a whole number, then 3 and 76,053,688.3333 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 | 228,161,065 | |
| -1 | -228,161,065 |
Let's try dividing by 4:
228,161,065 ÷ 4 = 57,040,266.25
If the quotient is a whole number, then 4 and 57,040,266.25 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 | 228,161,065 | |
| -1 | 228,161,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,103 | 3,761 | 5,515 | 12,133 | 18,805 | 41,371 | 60,665 | 206,855 | 4,148,383 | 20,741,915 | 45,632,213 | 228,161,065 |
| -1 | -5 | -11 | -55 | -1,103 | -3,761 | -5,515 | -12,133 | -18,805 | -41,371 | -60,665 | -206,855 | -4,148,383 | -20,741,915 | -45,632,213 | -228,161,065 |
