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 310,777,015, 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 | 310,777,015 | |
| -1 | -310,777,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,777,015.
Example:
1 x 310,777,015 = 310,777,015
and
-1 x -310,777,015 = 310,777,015
Notice both answers equal 310,777,015
With that explanation out of the way, let's continue. Next, we take the number 310,777,015 and divide it by 2:
310,777,015 ÷ 2 = 155,388,507.5
If the quotient is a whole number, then 2 and 155,388,507.5 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 | 310,777,015 | |
| -1 | -310,777,015 |
Now, we try dividing 310,777,015 by 3:
310,777,015 ÷ 3 = 103,592,338.3333
If the quotient is a whole number, then 3 and 103,592,338.3333 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 | 310,777,015 | |
| -1 | -310,777,015 |
Let's try dividing by 4:
310,777,015 ÷ 4 = 77,694,253.75
If the quotient is a whole number, then 4 and 77,694,253.75 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 | 310,777,015 | |
| -1 | 310,777,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 31 | 95 | 155 | 589 | 2,945 | 105,527 | 527,635 | 2,005,013 | 3,271,337 | 10,025,065 | 16,356,685 | 62,155,403 | 310,777,015 |
| -1 | -5 | -19 | -31 | -95 | -155 | -589 | -2,945 | -105,527 | -527,635 | -2,005,013 | -3,271,337 | -10,025,065 | -16,356,685 | -62,155,403 | -310,777,015 |
