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 310,204,013, 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 | 310,204,013 | |
| -1 | -310,204,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,204,013.
Example:
1 x 310,204,013 = 310,204,013
and
-1 x -310,204,013 = 310,204,013
Notice both answers equal 310,204,013
With that explanation out of the way, let's continue. Next, we take the number 310,204,013 and divide it by 2:
310,204,013 ÷ 2 = 155,102,006.5
If the quotient is a whole number, then 2 and 155,102,006.5 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 | 310,204,013 | |
| -1 | -310,204,013 |
Now, we try dividing 310,204,013 by 3:
310,204,013 ÷ 3 = 103,401,337.6667
If the quotient is a whole number, then 3 and 103,401,337.6667 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 | 310,204,013 | |
| -1 | -310,204,013 |
Let's try dividing by 4:
310,204,013 ÷ 4 = 77,551,003.25
If the quotient is a whole number, then 4 and 77,551,003.25 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 | 310,204,013 | |
| -1 | 310,204,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 529 | 3,059 | 3,703 | 4,409 | 10,051 | 30,863 | 70,357 | 83,771 | 101,407 | 586,397 | 709,849 | 1,926,733 | 2,332,361 | 13,487,131 | 16,326,527 | 44,314,859 | 310,204,013 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -529 | -3,059 | -3,703 | -4,409 | -10,051 | -30,863 | -70,357 | -83,771 | -101,407 | -586,397 | -709,849 | -1,926,733 | -2,332,361 | -13,487,131 | -16,326,527 | -44,314,859 | -310,204,013 |
