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 240,313,463, 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 | 240,313,463 | |
| -1 | -240,313,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,313,463.
Example:
1 x 240,313,463 = 240,313,463
and
-1 x -240,313,463 = 240,313,463
Notice both answers equal 240,313,463
With that explanation out of the way, let's continue. Next, we take the number 240,313,463 and divide it by 2:
240,313,463 ÷ 2 = 120,156,731.5
If the quotient is a whole number, then 2 and 120,156,731.5 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 | 240,313,463 | |
| -1 | -240,313,463 |
Now, we try dividing 240,313,463 by 3:
240,313,463 ÷ 3 = 80,104,487.6667
If the quotient is a whole number, then 3 and 80,104,487.6667 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 | 240,313,463 | |
| -1 | -240,313,463 |
Let's try dividing by 4:
240,313,463 ÷ 4 = 60,078,365.75
If the quotient is a whole number, then 4 and 60,078,365.75 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 | 240,313,463 | |
| -1 | 240,313,463 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 157 | 247 | 2,041 | 2,983 | 6,197 | 38,779 | 80,561 | 117,743 | 972,929 | 1,530,659 | 12,648,077 | 18,485,651 | 240,313,463 |
| -1 | -13 | -19 | -157 | -247 | -2,041 | -2,983 | -6,197 | -38,779 | -80,561 | -117,743 | -972,929 | -1,530,659 | -12,648,077 | -18,485,651 | -240,313,463 |
