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 313,005,533, 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 | 313,005,533 | |
| -1 | -313,005,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,005,533.
Example:
1 x 313,005,533 = 313,005,533
and
-1 x -313,005,533 = 313,005,533
Notice both answers equal 313,005,533
With that explanation out of the way, let's continue. Next, we take the number 313,005,533 and divide it by 2:
313,005,533 ÷ 2 = 156,502,766.5
If the quotient is a whole number, then 2 and 156,502,766.5 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 | 313,005,533 | |
| -1 | -313,005,533 |
Now, we try dividing 313,005,533 by 3:
313,005,533 ÷ 3 = 104,335,177.6667
If the quotient is a whole number, then 3 and 104,335,177.6667 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 | 313,005,533 | |
| -1 | -313,005,533 |
Let's try dividing by 4:
313,005,533 ÷ 4 = 78,251,383.25
If the quotient is a whole number, then 4 and 78,251,383.25 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 | 313,005,533 | |
| -1 | 313,005,533 |
If you did it right, you will end up with this table:
| 1 | 37 | 83 | 227 | 449 | 3,071 | 8,399 | 16,613 | 18,841 | 37,267 | 101,923 | 697,117 | 1,378,879 | 3,771,151 | 8,459,609 | 313,005,533 |
| -1 | -37 | -83 | -227 | -449 | -3,071 | -8,399 | -16,613 | -18,841 | -37,267 | -101,923 | -697,117 | -1,378,879 | -3,771,151 | -8,459,609 | -313,005,533 |
