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 311,203,235, 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 | 311,203,235 | |
| -1 | -311,203,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,203,235.
Example:
1 x 311,203,235 = 311,203,235
and
-1 x -311,203,235 = 311,203,235
Notice both answers equal 311,203,235
With that explanation out of the way, let's continue. Next, we take the number 311,203,235 and divide it by 2:
311,203,235 ÷ 2 = 155,601,617.5
If the quotient is a whole number, then 2 and 155,601,617.5 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 | 311,203,235 | |
| -1 | -311,203,235 |
Now, we try dividing 311,203,235 by 3:
311,203,235 ÷ 3 = 103,734,411.6667
If the quotient is a whole number, then 3 and 103,734,411.6667 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 | 311,203,235 | |
| -1 | -311,203,235 |
Let's try dividing by 4:
311,203,235 ÷ 4 = 77,800,808.75
If the quotient is a whole number, then 4 and 77,800,808.75 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 | 311,203,235 | |
| -1 | 311,203,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,307 | 6,535 | 6,803 | 9,149 | 34,015 | 45,745 | 47,621 | 238,105 | 8,891,521 | 44,457,605 | 62,240,647 | 311,203,235 |
| -1 | -5 | -7 | -35 | -1,307 | -6,535 | -6,803 | -9,149 | -34,015 | -45,745 | -47,621 | -238,105 | -8,891,521 | -44,457,605 | -62,240,647 | -311,203,235 |
