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 240,563,011, 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 | 240,563,011 | |
| -1 | -240,563,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,563,011.
Example:
1 x 240,563,011 = 240,563,011
and
-1 x -240,563,011 = 240,563,011
Notice both answers equal 240,563,011
With that explanation out of the way, let's continue. Next, we take the number 240,563,011 and divide it by 2:
240,563,011 ÷ 2 = 120,281,505.5
If the quotient is a whole number, then 2 and 120,281,505.5 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 | 240,563,011 | |
| -1 | -240,563,011 |
Now, we try dividing 240,563,011 by 3:
240,563,011 ÷ 3 = 80,187,670.3333
If the quotient is a whole number, then 3 and 80,187,670.3333 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 | 240,563,011 | |
| -1 | -240,563,011 |
Let's try dividing by 4:
240,563,011 ÷ 4 = 60,140,752.75
If the quotient is a whole number, then 4 and 60,140,752.75 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 | 240,563,011 | |
| -1 | 240,563,011 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 481 | 647 | 773 | 8,411 | 10,049 | 23,939 | 28,601 | 311,207 | 371,813 | 500,131 | 6,501,703 | 18,504,847 | 240,563,011 |
| -1 | -13 | -37 | -481 | -647 | -773 | -8,411 | -10,049 | -23,939 | -28,601 | -311,207 | -371,813 | -500,131 | -6,501,703 | -18,504,847 | -240,563,011 |
