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 240,171,551, 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 | 240,171,551 | |
| -1 | -240,171,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,171,551.
Example:
1 x 240,171,551 = 240,171,551
and
-1 x -240,171,551 = 240,171,551
Notice both answers equal 240,171,551
With that explanation out of the way, let's continue. Next, we take the number 240,171,551 and divide it by 2:
240,171,551 ÷ 2 = 120,085,775.5
If the quotient is a whole number, then 2 and 120,085,775.5 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 | 240,171,551 | |
| -1 | -240,171,551 |
Now, we try dividing 240,171,551 by 3:
240,171,551 ÷ 3 = 80,057,183.6667
If the quotient is a whole number, then 3 and 80,057,183.6667 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 | 240,171,551 | |
| -1 | -240,171,551 |
Let's try dividing by 4:
240,171,551 ÷ 4 = 60,042,887.75
If the quotient is a whole number, then 4 and 60,042,887.75 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 | 240,171,551 | |
| -1 | 240,171,551 |
If you did it right, you will end up with this table:
| 1 | 37 | 47 | 167 | 827 | 1,739 | 6,179 | 7,849 | 30,599 | 38,869 | 138,109 | 290,413 | 1,438,153 | 5,110,033 | 6,491,123 | 240,171,551 |
| -1 | -37 | -47 | -167 | -827 | -1,739 | -6,179 | -7,849 | -30,599 | -38,869 | -138,109 | -290,413 | -1,438,153 | -5,110,033 | -6,491,123 | -240,171,551 |
