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 240,163,505, 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 | 240,163,505 | |
| -1 | -240,163,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,163,505.
Example:
1 x 240,163,505 = 240,163,505
and
-1 x -240,163,505 = 240,163,505
Notice both answers equal 240,163,505
With that explanation out of the way, let's continue. Next, we take the number 240,163,505 and divide it by 2:
240,163,505 ÷ 2 = 120,081,752.5
If the quotient is a whole number, then 2 and 120,081,752.5 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 | 240,163,505 | |
| -1 | -240,163,505 |
Now, we try dividing 240,163,505 by 3:
240,163,505 ÷ 3 = 80,054,501.6667
If the quotient is a whole number, then 3 and 80,054,501.6667 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 | 240,163,505 | |
| -1 | -240,163,505 |
Let's try dividing by 4:
240,163,505 ÷ 4 = 60,040,876.25
If the quotient is a whole number, then 4 and 60,040,876.25 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 | 240,163,505 | |
| -1 | 240,163,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 139 | 695 | 2,363 | 11,815 | 20,327 | 101,635 | 345,559 | 1,727,795 | 2,825,453 | 14,127,265 | 48,032,701 | 240,163,505 |
| -1 | -5 | -17 | -85 | -139 | -695 | -2,363 | -11,815 | -20,327 | -101,635 | -345,559 | -1,727,795 | -2,825,453 | -14,127,265 | -48,032,701 | -240,163,505 |
