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 231,566,435, 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 | 231,566,435 | |
| -1 | -231,566,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,566,435.
Example:
1 x 231,566,435 = 231,566,435
and
-1 x -231,566,435 = 231,566,435
Notice both answers equal 231,566,435
With that explanation out of the way, let's continue. Next, we take the number 231,566,435 and divide it by 2:
231,566,435 ÷ 2 = 115,783,217.5
If the quotient is a whole number, then 2 and 115,783,217.5 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 | 231,566,435 | |
| -1 | -231,566,435 |
Now, we try dividing 231,566,435 by 3:
231,566,435 ÷ 3 = 77,188,811.6667
If the quotient is a whole number, then 3 and 77,188,811.6667 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 | 231,566,435 | |
| -1 | -231,566,435 |
Let's try dividing by 4:
231,566,435 ÷ 4 = 57,891,608.75
If the quotient is a whole number, then 4 and 57,891,608.75 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 | 231,566,435 | |
| -1 | 231,566,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 87,881 | 439,405 | 1,493,977 | 2,724,311 | 7,469,885 | 13,621,555 | 46,313,287 | 231,566,435 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -87,881 | -439,405 | -1,493,977 | -2,724,311 | -7,469,885 | -13,621,555 | -46,313,287 | -231,566,435 |
