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 240,456,055, 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 | 240,456,055 | |
| -1 | -240,456,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,456,055.
Example:
1 x 240,456,055 = 240,456,055
and
-1 x -240,456,055 = 240,456,055
Notice both answers equal 240,456,055
With that explanation out of the way, let's continue. Next, we take the number 240,456,055 and divide it by 2:
240,456,055 ÷ 2 = 120,228,027.5
If the quotient is a whole number, then 2 and 120,228,027.5 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 | 240,456,055 | |
| -1 | -240,456,055 |
Now, we try dividing 240,456,055 by 3:
240,456,055 ÷ 3 = 80,152,018.3333
If the quotient is a whole number, then 3 and 80,152,018.3333 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 | 240,456,055 | |
| -1 | -240,456,055 |
Let's try dividing by 4:
240,456,055 ÷ 4 = 60,114,013.75
If the quotient is a whole number, then 4 and 60,114,013.75 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 | 240,456,055 | |
| -1 | 240,456,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 96,763 | 483,815 | 677,341 | 3,386,705 | 6,870,173 | 34,350,865 | 48,091,211 | 240,456,055 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -96,763 | -483,815 | -677,341 | -3,386,705 | -6,870,173 | -34,350,865 | -48,091,211 | -240,456,055 |
