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 240,533,663, 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 | 240,533,663 | |
| -1 | -240,533,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,533,663.
Example:
1 x 240,533,663 = 240,533,663
and
-1 x -240,533,663 = 240,533,663
Notice both answers equal 240,533,663
With that explanation out of the way, let's continue. Next, we take the number 240,533,663 and divide it by 2:
240,533,663 ÷ 2 = 120,266,831.5
If the quotient is a whole number, then 2 and 120,266,831.5 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 | 240,533,663 | |
| -1 | -240,533,663 |
Now, we try dividing 240,533,663 by 3:
240,533,663 ÷ 3 = 80,177,887.6667
If the quotient is a whole number, then 3 and 80,177,887.6667 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 | 240,533,663 | |
| -1 | -240,533,663 |
Let's try dividing by 4:
240,533,663 ÷ 4 = 60,133,415.75
If the quotient is a whole number, then 4 and 60,133,415.75 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 | 240,533,663 | |
| -1 | 240,533,663 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 239 | 901 | 1,117 | 4,063 | 12,667 | 18,989 | 59,201 | 215,339 | 266,963 | 1,006,417 | 4,538,371 | 14,149,039 | 240,533,663 |
| -1 | -17 | -53 | -239 | -901 | -1,117 | -4,063 | -12,667 | -18,989 | -59,201 | -215,339 | -266,963 | -1,006,417 | -4,538,371 | -14,149,039 | -240,533,663 |
