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 313,552,015, 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 | 313,552,015 | |
| -1 | -313,552,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,552,015.
Example:
1 x 313,552,015 = 313,552,015
and
-1 x -313,552,015 = 313,552,015
Notice both answers equal 313,552,015
With that explanation out of the way, let's continue. Next, we take the number 313,552,015 and divide it by 2:
313,552,015 ÷ 2 = 156,776,007.5
If the quotient is a whole number, then 2 and 156,776,007.5 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 | 313,552,015 | |
| -1 | -313,552,015 |
Now, we try dividing 313,552,015 by 3:
313,552,015 ÷ 3 = 104,517,338.3333
If the quotient is a whole number, then 3 and 104,517,338.3333 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 | 313,552,015 | |
| -1 | -313,552,015 |
Let's try dividing by 4:
313,552,015 ÷ 4 = 78,388,003.75
If the quotient is a whole number, then 4 and 78,388,003.75 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 | 313,552,015 | |
| -1 | 313,552,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 97 | 485 | 679 | 3,395 | 92,357 | 461,785 | 646,499 | 3,232,495 | 8,958,629 | 44,793,145 | 62,710,403 | 313,552,015 |
| -1 | -5 | -7 | -35 | -97 | -485 | -679 | -3,395 | -92,357 | -461,785 | -646,499 | -3,232,495 | -8,958,629 | -44,793,145 | -62,710,403 | -313,552,015 |
