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 311,136,455, 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 | 311,136,455 | |
| -1 | -311,136,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,136,455.
Example:
1 x 311,136,455 = 311,136,455
and
-1 x -311,136,455 = 311,136,455
Notice both answers equal 311,136,455
With that explanation out of the way, let's continue. Next, we take the number 311,136,455 and divide it by 2:
311,136,455 ÷ 2 = 155,568,227.5
If the quotient is a whole number, then 2 and 155,568,227.5 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 | 311,136,455 | |
| -1 | -311,136,455 |
Now, we try dividing 311,136,455 by 3:
311,136,455 ÷ 3 = 103,712,151.6667
If the quotient is a whole number, then 3 and 103,712,151.6667 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 | 311,136,455 | |
| -1 | -311,136,455 |
Let's try dividing by 4:
311,136,455 ÷ 4 = 77,784,113.75
If the quotient is a whole number, then 4 and 77,784,113.75 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 | 311,136,455 | |
| -1 | 311,136,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 271 | 1,355 | 1,897 | 9,485 | 32,803 | 164,015 | 229,621 | 1,148,105 | 8,889,613 | 44,448,065 | 62,227,291 | 311,136,455 |
| -1 | -5 | -7 | -35 | -271 | -1,355 | -1,897 | -9,485 | -32,803 | -164,015 | -229,621 | -1,148,105 | -8,889,613 | -44,448,065 | -62,227,291 | -311,136,455 |
