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 240,236,437, 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 | 240,236,437 | |
| -1 | -240,236,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,236,437.
Example:
1 x 240,236,437 = 240,236,437
and
-1 x -240,236,437 = 240,236,437
Notice both answers equal 240,236,437
With that explanation out of the way, let's continue. Next, we take the number 240,236,437 and divide it by 2:
240,236,437 ÷ 2 = 120,118,218.5
If the quotient is a whole number, then 2 and 120,118,218.5 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 | 240,236,437 | |
| -1 | -240,236,437 |
Now, we try dividing 240,236,437 by 3:
240,236,437 ÷ 3 = 80,078,812.3333
If the quotient is a whole number, then 3 and 80,078,812.3333 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 | 240,236,437 | |
| -1 | -240,236,437 |
Let's try dividing by 4:
240,236,437 ÷ 4 = 60,059,109.25
If the quotient is a whole number, then 4 and 60,059,109.25 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 | 240,236,437 | |
| -1 | 240,236,437 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 179 | 1,253 | 3,401 | 10,091 | 23,807 | 70,637 | 191,729 | 1,342,103 | 1,806,289 | 12,644,023 | 34,319,491 | 240,236,437 |
| -1 | -7 | -19 | -133 | -179 | -1,253 | -3,401 | -10,091 | -23,807 | -70,637 | -191,729 | -1,342,103 | -1,806,289 | -12,644,023 | -34,319,491 | -240,236,437 |
