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 240,833,515, 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 | 240,833,515 | |
| -1 | -240,833,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,833,515.
Example:
1 x 240,833,515 = 240,833,515
and
-1 x -240,833,515 = 240,833,515
Notice both answers equal 240,833,515
With that explanation out of the way, let's continue. Next, we take the number 240,833,515 and divide it by 2:
240,833,515 ÷ 2 = 120,416,757.5
If the quotient is a whole number, then 2 and 120,416,757.5 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 | 240,833,515 | |
| -1 | -240,833,515 |
Now, we try dividing 240,833,515 by 3:
240,833,515 ÷ 3 = 80,277,838.3333
If the quotient is a whole number, then 3 and 80,277,838.3333 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 | 240,833,515 | |
| -1 | -240,833,515 |
Let's try dividing by 4:
240,833,515 ÷ 4 = 60,208,378.75
If the quotient is a whole number, then 4 and 60,208,378.75 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 | 240,833,515 | |
| -1 | 240,833,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 409 | 2,045 | 5,317 | 9,059 | 26,585 | 45,295 | 117,767 | 588,835 | 3,705,131 | 18,525,655 | 48,166,703 | 240,833,515 |
| -1 | -5 | -13 | -65 | -409 | -2,045 | -5,317 | -9,059 | -26,585 | -45,295 | -117,767 | -588,835 | -3,705,131 | -18,525,655 | -48,166,703 | -240,833,515 |
