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 240,242,453, 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 | 240,242,453 | |
| -1 | -240,242,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,242,453.
Example:
1 x 240,242,453 = 240,242,453
and
-1 x -240,242,453 = 240,242,453
Notice both answers equal 240,242,453
With that explanation out of the way, let's continue. Next, we take the number 240,242,453 and divide it by 2:
240,242,453 ÷ 2 = 120,121,226.5
If the quotient is a whole number, then 2 and 120,121,226.5 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 | 240,242,453 | |
| -1 | -240,242,453 |
Now, we try dividing 240,242,453 by 3:
240,242,453 ÷ 3 = 80,080,817.6667
If the quotient is a whole number, then 3 and 80,080,817.6667 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 | 240,242,453 | |
| -1 | -240,242,453 |
Let's try dividing by 4:
240,242,453 ÷ 4 = 60,060,613.25
If the quotient is a whole number, then 4 and 60,060,613.25 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 | 240,242,453 | |
| -1 | 240,242,453 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 103 | 187 | 1,133 | 1,751 | 12,473 | 19,261 | 137,203 | 212,041 | 1,284,719 | 2,332,451 | 14,131,909 | 21,840,223 | 240,242,453 |
| -1 | -11 | -17 | -103 | -187 | -1,133 | -1,751 | -12,473 | -19,261 | -137,203 | -212,041 | -1,284,719 | -2,332,451 | -14,131,909 | -21,840,223 | -240,242,453 |
