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 235,341,455, 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 | 235,341,455 | |
| -1 | -235,341,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,341,455.
Example:
1 x 235,341,455 = 235,341,455
and
-1 x -235,341,455 = 235,341,455
Notice both answers equal 235,341,455
With that explanation out of the way, let's continue. Next, we take the number 235,341,455 and divide it by 2:
235,341,455 ÷ 2 = 117,670,727.5
If the quotient is a whole number, then 2 and 117,670,727.5 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 | 235,341,455 | |
| -1 | -235,341,455 |
Now, we try dividing 235,341,455 by 3:
235,341,455 ÷ 3 = 78,447,151.6667
If the quotient is a whole number, then 3 and 78,447,151.6667 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 | 235,341,455 | |
| -1 | -235,341,455 |
Let's try dividing by 4:
235,341,455 ÷ 4 = 58,835,363.75
If the quotient is a whole number, then 4 and 58,835,363.75 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 | 235,341,455 | |
| -1 | 235,341,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 799 | 3,995 | 58,909 | 294,545 | 1,001,453 | 2,768,723 | 5,007,265 | 13,843,615 | 47,068,291 | 235,341,455 |
| -1 | -5 | -17 | -47 | -85 | -235 | -799 | -3,995 | -58,909 | -294,545 | -1,001,453 | -2,768,723 | -5,007,265 | -13,843,615 | -47,068,291 | -235,341,455 |
