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 240,236,735, 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 | 240,236,735 | |
| -1 | -240,236,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,236,735.
Example:
1 x 240,236,735 = 240,236,735
and
-1 x -240,236,735 = 240,236,735
Notice both answers equal 240,236,735
With that explanation out of the way, let's continue. Next, we take the number 240,236,735 and divide it by 2:
240,236,735 ÷ 2 = 120,118,367.5
If the quotient is a whole number, then 2 and 120,118,367.5 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 | 240,236,735 | |
| -1 | -240,236,735 |
Now, we try dividing 240,236,735 by 3:
240,236,735 ÷ 3 = 80,078,911.6667
If the quotient is a whole number, then 3 and 80,078,911.6667 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 | 240,236,735 | |
| -1 | -240,236,735 |
Let's try dividing by 4:
240,236,735 ÷ 4 = 60,059,183.75
If the quotient is a whole number, then 4 and 60,059,183.75 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 | 240,236,735 | |
| -1 | 240,236,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 281 | 815 | 1,049 | 1,405 | 5,245 | 45,803 | 170,987 | 229,015 | 294,769 | 854,935 | 1,473,845 | 48,047,347 | 240,236,735 |
| -1 | -5 | -163 | -281 | -815 | -1,049 | -1,405 | -5,245 | -45,803 | -170,987 | -229,015 | -294,769 | -854,935 | -1,473,845 | -48,047,347 | -240,236,735 |
