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 310,233,235, 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 | 310,233,235 | |
| -1 | -310,233,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,233,235.
Example:
1 x 310,233,235 = 310,233,235
and
-1 x -310,233,235 = 310,233,235
Notice both answers equal 310,233,235
With that explanation out of the way, let's continue. Next, we take the number 310,233,235 and divide it by 2:
310,233,235 ÷ 2 = 155,116,617.5
If the quotient is a whole number, then 2 and 155,116,617.5 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 | 310,233,235 | |
| -1 | -310,233,235 |
Now, we try dividing 310,233,235 by 3:
310,233,235 ÷ 3 = 103,411,078.3333
If the quotient is a whole number, then 3 and 103,411,078.3333 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 | 310,233,235 | |
| -1 | -310,233,235 |
Let's try dividing by 4:
310,233,235 ÷ 4 = 77,558,308.75
If the quotient is a whole number, then 4 and 77,558,308.75 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 | 310,233,235 | |
| -1 | 310,233,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 251,201 | 1,256,005 | 3,265,613 | 4,772,819 | 16,328,065 | 23,864,095 | 62,046,647 | 310,233,235 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -251,201 | -1,256,005 | -3,265,613 | -4,772,819 | -16,328,065 | -23,864,095 | -62,046,647 | -310,233,235 |
