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 240,131,111, 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 | 240,131,111 | |
| -1 | -240,131,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,131,111.
Example:
1 x 240,131,111 = 240,131,111
and
-1 x -240,131,111 = 240,131,111
Notice both answers equal 240,131,111
With that explanation out of the way, let's continue. Next, we take the number 240,131,111 and divide it by 2:
240,131,111 ÷ 2 = 120,065,555.5
If the quotient is a whole number, then 2 and 120,065,555.5 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 | 240,131,111 | |
| -1 | -240,131,111 |
Now, we try dividing 240,131,111 by 3:
240,131,111 ÷ 3 = 80,043,703.6667
If the quotient is a whole number, then 3 and 80,043,703.6667 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 | 240,131,111 | |
| -1 | -240,131,111 |
Let's try dividing by 4:
240,131,111 ÷ 4 = 60,032,777.75
If the quotient is a whole number, then 4 and 60,032,777.75 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 | 240,131,111 | |
| -1 | 240,131,111 |
If you did it right, you will end up with this table:
| 1 | 11 | 163 | 199 | 673 | 1,793 | 2,189 | 7,403 | 32,437 | 109,699 | 133,927 | 356,807 | 1,206,689 | 1,473,197 | 21,830,101 | 240,131,111 |
| -1 | -11 | -163 | -199 | -673 | -1,793 | -2,189 | -7,403 | -32,437 | -109,699 | -133,927 | -356,807 | -1,206,689 | -1,473,197 | -21,830,101 | -240,131,111 |
