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 228,485,105, 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 | 228,485,105 | |
| -1 | -228,485,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,485,105.
Example:
1 x 228,485,105 = 228,485,105
and
-1 x -228,485,105 = 228,485,105
Notice both answers equal 228,485,105
With that explanation out of the way, let's continue. Next, we take the number 228,485,105 and divide it by 2:
228,485,105 ÷ 2 = 114,242,552.5
If the quotient is a whole number, then 2 and 114,242,552.5 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 | 228,485,105 | |
| -1 | -228,485,105 |
Now, we try dividing 228,485,105 by 3:
228,485,105 ÷ 3 = 76,161,701.6667
If the quotient is a whole number, then 3 and 76,161,701.6667 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 | 228,485,105 | |
| -1 | -228,485,105 |
Let's try dividing by 4:
228,485,105 ÷ 4 = 57,121,276.25
If the quotient is a whole number, then 4 and 57,121,276.25 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 | 228,485,105 | |
| -1 | 228,485,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 563 | 2,815 | 3,529 | 12,949 | 17,645 | 64,745 | 81,167 | 405,835 | 1,986,827 | 9,934,135 | 45,697,021 | 228,485,105 |
| -1 | -5 | -23 | -115 | -563 | -2,815 | -3,529 | -12,949 | -17,645 | -64,745 | -81,167 | -405,835 | -1,986,827 | -9,934,135 | -45,697,021 | -228,485,105 |
