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 311,073,377, 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 | 311,073,377 | |
| -1 | -311,073,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,073,377.
Example:
1 x 311,073,377 = 311,073,377
and
-1 x -311,073,377 = 311,073,377
Notice both answers equal 311,073,377
With that explanation out of the way, let's continue. Next, we take the number 311,073,377 and divide it by 2:
311,073,377 ÷ 2 = 155,536,688.5
If the quotient is a whole number, then 2 and 155,536,688.5 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 | 311,073,377 | |
| -1 | -311,073,377 |
Now, we try dividing 311,073,377 by 3:
311,073,377 ÷ 3 = 103,691,125.6667
If the quotient is a whole number, then 3 and 103,691,125.6667 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 | 311,073,377 | |
| -1 | -311,073,377 |
Let's try dividing by 4:
311,073,377 ÷ 4 = 77,768,344.25
If the quotient is a whole number, then 4 and 77,768,344.25 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 | 311,073,377 | |
| -1 | 311,073,377 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 541 | 571 | 1,007 | 10,279 | 10,849 | 28,673 | 30,263 | 308,911 | 544,787 | 574,997 | 5,869,309 | 16,372,283 | 311,073,377 |
| -1 | -19 | -53 | -541 | -571 | -1,007 | -10,279 | -10,849 | -28,673 | -30,263 | -308,911 | -544,787 | -574,997 | -5,869,309 | -16,372,283 | -311,073,377 |
