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 311,395, 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 | 311,395 | |
| -1 | -311,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,395.
Example:
1 x 311,395 = 311,395
and
-1 x -311,395 = 311,395
Notice both answers equal 311,395
With that explanation out of the way, let's continue. Next, we take the number 311,395 and divide it by 2:
311,395 ÷ 2 = 155,697.5
If the quotient is a whole number, then 2 and 155,697.5 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 | 311,395 | |
| -1 | -311,395 |
Now, we try dividing 311,395 by 3:
311,395 ÷ 3 = 103,798.3333
If the quotient is a whole number, then 3 and 103,798.3333 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 | 311,395 | |
| -1 | -311,395 |
Let's try dividing by 4:
311,395 ÷ 4 = 77,848.75
If the quotient is a whole number, then 4 and 77,848.75 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 | 311,395 | |
| -1 | 311,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 41 | 49 | 155 | 205 | 217 | 245 | 287 | 1,085 | 1,271 | 1,435 | 1,519 | 2,009 | 6,355 | 7,595 | 8,897 | 10,045 | 44,485 | 62,279 | 311,395 |
| -1 | -5 | -7 | -31 | -35 | -41 | -49 | -155 | -205 | -217 | -245 | -287 | -1,085 | -1,271 | -1,435 | -1,519 | -2,009 | -6,355 | -7,595 | -8,897 | -10,045 | -44,485 | -62,279 | -311,395 |
