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 311,427,055, 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 | 311,427,055 | |
| -1 | -311,427,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,427,055.
Example:
1 x 311,427,055 = 311,427,055
and
-1 x -311,427,055 = 311,427,055
Notice both answers equal 311,427,055
With that explanation out of the way, let's continue. Next, we take the number 311,427,055 and divide it by 2:
311,427,055 ÷ 2 = 155,713,527.5
If the quotient is a whole number, then 2 and 155,713,527.5 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 | 311,427,055 | |
| -1 | -311,427,055 |
Now, we try dividing 311,427,055 by 3:
311,427,055 ÷ 3 = 103,809,018.3333
If the quotient is a whole number, then 3 and 103,809,018.3333 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 | 311,427,055 | |
| -1 | -311,427,055 |
Let's try dividing by 4:
311,427,055 ÷ 4 = 77,856,763.75
If the quotient is a whole number, then 4 and 77,856,763.75 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 | 311,427,055 | |
| -1 | 311,427,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 557 | 1,669 | 2,785 | 8,345 | 37,319 | 111,823 | 186,595 | 559,115 | 929,633 | 4,648,165 | 62,285,411 | 311,427,055 |
| -1 | -5 | -67 | -335 | -557 | -1,669 | -2,785 | -8,345 | -37,319 | -111,823 | -186,595 | -559,115 | -929,633 | -4,648,165 | -62,285,411 | -311,427,055 |
