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 235,006,585, 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 | 235,006,585 | |
| -1 | -235,006,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,006,585.
Example:
1 x 235,006,585 = 235,006,585
and
-1 x -235,006,585 = 235,006,585
Notice both answers equal 235,006,585
With that explanation out of the way, let's continue. Next, we take the number 235,006,585 and divide it by 2:
235,006,585 ÷ 2 = 117,503,292.5
If the quotient is a whole number, then 2 and 117,503,292.5 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 | 235,006,585 | |
| -1 | -235,006,585 |
Now, we try dividing 235,006,585 by 3:
235,006,585 ÷ 3 = 78,335,528.3333
If the quotient is a whole number, then 3 and 78,335,528.3333 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 | 235,006,585 | |
| -1 | -235,006,585 |
Let's try dividing by 4:
235,006,585 ÷ 4 = 58,751,646.25
If the quotient is a whole number, then 4 and 58,751,646.25 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 | 235,006,585 | |
| -1 | 235,006,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 151 | 755 | 1,661 | 8,305 | 28,297 | 141,485 | 311,267 | 1,556,335 | 4,272,847 | 21,364,235 | 47,001,317 | 235,006,585 |
| -1 | -5 | -11 | -55 | -151 | -755 | -1,661 | -8,305 | -28,297 | -141,485 | -311,267 | -1,556,335 | -4,272,847 | -21,364,235 | -47,001,317 | -235,006,585 |
