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 313,327,261, 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 | 313,327,261 | |
| -1 | -313,327,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,327,261.
Example:
1 x 313,327,261 = 313,327,261
and
-1 x -313,327,261 = 313,327,261
Notice both answers equal 313,327,261
With that explanation out of the way, let's continue. Next, we take the number 313,327,261 and divide it by 2:
313,327,261 ÷ 2 = 156,663,630.5
If the quotient is a whole number, then 2 and 156,663,630.5 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 | 313,327,261 | |
| -1 | -313,327,261 |
Now, we try dividing 313,327,261 by 3:
313,327,261 ÷ 3 = 104,442,420.3333
If the quotient is a whole number, then 3 and 104,442,420.3333 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 | 313,327,261 | |
| -1 | -313,327,261 |
Let's try dividing by 4:
313,327,261 ÷ 4 = 78,331,815.25
If the quotient is a whole number, then 4 and 78,331,815.25 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 | 313,327,261 | |
| -1 | 313,327,261 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 403 | 821 | 947 | 10,673 | 12,311 | 25,451 | 29,357 | 330,863 | 381,641 | 777,487 | 10,107,331 | 24,102,097 | 313,327,261 |
| -1 | -13 | -31 | -403 | -821 | -947 | -10,673 | -12,311 | -25,451 | -29,357 | -330,863 | -381,641 | -777,487 | -10,107,331 | -24,102,097 | -313,327,261 |
