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 228,162,265, 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 | 228,162,265 | |
| -1 | -228,162,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,162,265.
Example:
1 x 228,162,265 = 228,162,265
and
-1 x -228,162,265 = 228,162,265
Notice both answers equal 228,162,265
With that explanation out of the way, let's continue. Next, we take the number 228,162,265 and divide it by 2:
228,162,265 ÷ 2 = 114,081,132.5
If the quotient is a whole number, then 2 and 114,081,132.5 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 | 228,162,265 | |
| -1 | -228,162,265 |
Now, we try dividing 228,162,265 by 3:
228,162,265 ÷ 3 = 76,054,088.3333
If the quotient is a whole number, then 3 and 76,054,088.3333 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 | 228,162,265 | |
| -1 | -228,162,265 |
Let's try dividing by 4:
228,162,265 ÷ 4 = 57,040,566.25
If the quotient is a whole number, then 4 and 57,040,566.25 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 | 228,162,265 | |
| -1 | 228,162,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 181 | 305 | 905 | 4,133 | 11,041 | 20,665 | 55,205 | 252,113 | 748,073 | 1,260,565 | 3,740,365 | 45,632,453 | 228,162,265 |
| -1 | -5 | -61 | -181 | -305 | -905 | -4,133 | -11,041 | -20,665 | -55,205 | -252,113 | -748,073 | -1,260,565 | -3,740,365 | -45,632,453 | -228,162,265 |
