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 235,081,685, 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 | 235,081,685 | |
| -1 | -235,081,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,081,685.
Example:
1 x 235,081,685 = 235,081,685
and
-1 x -235,081,685 = 235,081,685
Notice both answers equal 235,081,685
With that explanation out of the way, let's continue. Next, we take the number 235,081,685 and divide it by 2:
235,081,685 ÷ 2 = 117,540,842.5
If the quotient is a whole number, then 2 and 117,540,842.5 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 | 235,081,685 | |
| -1 | -235,081,685 |
Now, we try dividing 235,081,685 by 3:
235,081,685 ÷ 3 = 78,360,561.6667
If the quotient is a whole number, then 3 and 78,360,561.6667 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 | 235,081,685 | |
| -1 | -235,081,685 |
Let's try dividing by 4:
235,081,685 ÷ 4 = 58,770,421.25
If the quotient is a whole number, then 4 and 58,770,421.25 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 | 235,081,685 | |
| -1 | 235,081,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 199 | 995 | 5,771 | 8,147 | 28,855 | 40,735 | 236,263 | 1,181,315 | 1,621,253 | 8,106,265 | 47,016,337 | 235,081,685 |
| -1 | -5 | -29 | -145 | -199 | -995 | -5,771 | -8,147 | -28,855 | -40,735 | -236,263 | -1,181,315 | -1,621,253 | -8,106,265 | -47,016,337 | -235,081,685 |
