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 240,523,355, 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 | 240,523,355 | |
| -1 | -240,523,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,523,355.
Example:
1 x 240,523,355 = 240,523,355
and
-1 x -240,523,355 = 240,523,355
Notice both answers equal 240,523,355
With that explanation out of the way, let's continue. Next, we take the number 240,523,355 and divide it by 2:
240,523,355 ÷ 2 = 120,261,677.5
If the quotient is a whole number, then 2 and 120,261,677.5 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 | 240,523,355 | |
| -1 | -240,523,355 |
Now, we try dividing 240,523,355 by 3:
240,523,355 ÷ 3 = 80,174,451.6667
If the quotient is a whole number, then 3 and 80,174,451.6667 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 | 240,523,355 | |
| -1 | -240,523,355 |
Let's try dividing by 4:
240,523,355 ÷ 4 = 60,130,838.75
If the quotient is a whole number, then 4 and 60,130,838.75 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 | 240,523,355 | |
| -1 | 240,523,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 193 | 281 | 887 | 965 | 1,405 | 4,435 | 54,233 | 171,191 | 249,247 | 271,165 | 855,955 | 1,246,235 | 48,104,671 | 240,523,355 |
| -1 | -5 | -193 | -281 | -887 | -965 | -1,405 | -4,435 | -54,233 | -171,191 | -249,247 | -271,165 | -855,955 | -1,246,235 | -48,104,671 | -240,523,355 |
