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 310,334,011, 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 | 310,334,011 | |
| -1 | -310,334,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,334,011.
Example:
1 x 310,334,011 = 310,334,011
and
-1 x -310,334,011 = 310,334,011
Notice both answers equal 310,334,011
With that explanation out of the way, let's continue. Next, we take the number 310,334,011 and divide it by 2:
310,334,011 ÷ 2 = 155,167,005.5
If the quotient is a whole number, then 2 and 155,167,005.5 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 | 310,334,011 | |
| -1 | -310,334,011 |
Now, we try dividing 310,334,011 by 3:
310,334,011 ÷ 3 = 103,444,670.3333
If the quotient is a whole number, then 3 and 103,444,670.3333 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 | 310,334,011 | |
| -1 | -310,334,011 |
Let's try dividing by 4:
310,334,011 ÷ 4 = 77,583,502.75
If the quotient is a whole number, then 4 and 77,583,502.75 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 | 310,334,011 | |
| -1 | 310,334,011 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 89 | 247 | 361 | 743 | 1,157 | 1,691 | 4,693 | 9,659 | 14,117 | 21,983 | 32,129 | 66,127 | 183,521 | 268,223 | 417,677 | 859,651 | 1,256,413 | 3,486,899 | 16,333,369 | 23,871,847 | 310,334,011 |
| -1 | -13 | -19 | -89 | -247 | -361 | -743 | -1,157 | -1,691 | -4,693 | -9,659 | -14,117 | -21,983 | -32,129 | -66,127 | -183,521 | -268,223 | -417,677 | -859,651 | -1,256,413 | -3,486,899 | -16,333,369 | -23,871,847 | -310,334,011 |
