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 310,020,335, 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 | 310,020,335 | |
| -1 | -310,020,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,020,335.
Example:
1 x 310,020,335 = 310,020,335
and
-1 x -310,020,335 = 310,020,335
Notice both answers equal 310,020,335
With that explanation out of the way, let's continue. Next, we take the number 310,020,335 and divide it by 2:
310,020,335 ÷ 2 = 155,010,167.5
If the quotient is a whole number, then 2 and 155,010,167.5 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 | 310,020,335 | |
| -1 | -310,020,335 |
Now, we try dividing 310,020,335 by 3:
310,020,335 ÷ 3 = 103,340,111.6667
If the quotient is a whole number, then 3 and 103,340,111.6667 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 | 310,020,335 | |
| -1 | -310,020,335 |
Let's try dividing by 4:
310,020,335 ÷ 4 = 77,505,083.75
If the quotient is a whole number, then 4 and 77,505,083.75 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 | 310,020,335 | |
| -1 | 310,020,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 127 | 635 | 2,921 | 14,605 | 21,227 | 106,135 | 488,221 | 2,441,105 | 2,695,829 | 13,479,145 | 62,004,067 | 310,020,335 |
| -1 | -5 | -23 | -115 | -127 | -635 | -2,921 | -14,605 | -21,227 | -106,135 | -488,221 | -2,441,105 | -2,695,829 | -13,479,145 | -62,004,067 | -310,020,335 |
