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 240,233,663, 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 | 240,233,663 | |
| -1 | -240,233,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,233,663.
Example:
1 x 240,233,663 = 240,233,663
and
-1 x -240,233,663 = 240,233,663
Notice both answers equal 240,233,663
With that explanation out of the way, let's continue. Next, we take the number 240,233,663 and divide it by 2:
240,233,663 ÷ 2 = 120,116,831.5
If the quotient is a whole number, then 2 and 120,116,831.5 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 | 240,233,663 | |
| -1 | -240,233,663 |
Now, we try dividing 240,233,663 by 3:
240,233,663 ÷ 3 = 80,077,887.6667
If the quotient is a whole number, then 3 and 80,077,887.6667 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 | 240,233,663 | |
| -1 | -240,233,663 |
Let's try dividing by 4:
240,233,663 ÷ 4 = 60,058,415.75
If the quotient is a whole number, then 4 and 60,058,415.75 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 | 240,233,663 | |
| -1 | 240,233,663 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 59 | 223 | 589 | 961 | 1,121 | 1,829 | 4,237 | 6,913 | 13,157 | 18,259 | 34,751 | 56,699 | 131,347 | 214,303 | 249,983 | 407,867 | 1,077,281 | 4,071,757 | 7,749,473 | 12,643,877 | 240,233,663 |
| -1 | -19 | -31 | -59 | -223 | -589 | -961 | -1,121 | -1,829 | -4,237 | -6,913 | -13,157 | -18,259 | -34,751 | -56,699 | -131,347 | -214,303 | -249,983 | -407,867 | -1,077,281 | -4,071,757 | -7,749,473 | -12,643,877 | -240,233,663 |
