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 235,237,835, 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 | 235,237,835 | |
| -1 | -235,237,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,237,835.
Example:
1 x 235,237,835 = 235,237,835
and
-1 x -235,237,835 = 235,237,835
Notice both answers equal 235,237,835
With that explanation out of the way, let's continue. Next, we take the number 235,237,835 and divide it by 2:
235,237,835 ÷ 2 = 117,618,917.5
If the quotient is a whole number, then 2 and 117,618,917.5 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 | 235,237,835 | |
| -1 | -235,237,835 |
Now, we try dividing 235,237,835 by 3:
235,237,835 ÷ 3 = 78,412,611.6667
If the quotient is a whole number, then 3 and 78,412,611.6667 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 | 235,237,835 | |
| -1 | -235,237,835 |
Let's try dividing by 4:
235,237,835 ÷ 4 = 58,809,458.75
If the quotient is a whole number, then 4 and 58,809,458.75 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 | 235,237,835 | |
| -1 | 235,237,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 449 | 2,245 | 3,143 | 14,969 | 15,715 | 74,845 | 104,783 | 523,915 | 6,721,081 | 33,605,405 | 47,047,567 | 235,237,835 |
| -1 | -5 | -7 | -35 | -449 | -2,245 | -3,143 | -14,969 | -15,715 | -74,845 | -104,783 | -523,915 | -6,721,081 | -33,605,405 | -47,047,567 | -235,237,835 |
