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 235,354,055, 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 | 235,354,055 | |
| -1 | -235,354,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,354,055.
Example:
1 x 235,354,055 = 235,354,055
and
-1 x -235,354,055 = 235,354,055
Notice both answers equal 235,354,055
With that explanation out of the way, let's continue. Next, we take the number 235,354,055 and divide it by 2:
235,354,055 ÷ 2 = 117,677,027.5
If the quotient is a whole number, then 2 and 117,677,027.5 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 | 235,354,055 | |
| -1 | -235,354,055 |
Now, we try dividing 235,354,055 by 3:
235,354,055 ÷ 3 = 78,451,351.6667
If the quotient is a whole number, then 3 and 78,451,351.6667 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 | 235,354,055 | |
| -1 | -235,354,055 |
Let's try dividing by 4:
235,354,055 ÷ 4 = 58,838,513.75
If the quotient is a whole number, then 4 and 58,838,513.75 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 | 235,354,055 | |
| -1 | 235,354,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 239 | 1,195 | 5,497 | 8,563 | 27,485 | 42,815 | 196,949 | 984,745 | 2,046,557 | 10,232,785 | 47,070,811 | 235,354,055 |
| -1 | -5 | -23 | -115 | -239 | -1,195 | -5,497 | -8,563 | -27,485 | -42,815 | -196,949 | -984,745 | -2,046,557 | -10,232,785 | -47,070,811 | -235,354,055 |
