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 313,035,821, 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 | 313,035,821 | |
| -1 | -313,035,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,035,821.
Example:
1 x 313,035,821 = 313,035,821
and
-1 x -313,035,821 = 313,035,821
Notice both answers equal 313,035,821
With that explanation out of the way, let's continue. Next, we take the number 313,035,821 and divide it by 2:
313,035,821 ÷ 2 = 156,517,910.5
If the quotient is a whole number, then 2 and 156,517,910.5 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 | 313,035,821 | |
| -1 | -313,035,821 |
Now, we try dividing 313,035,821 by 3:
313,035,821 ÷ 3 = 104,345,273.6667
If the quotient is a whole number, then 3 and 104,345,273.6667 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 | 313,035,821 | |
| -1 | -313,035,821 |
Let's try dividing by 4:
313,035,821 ÷ 4 = 78,258,955.25
If the quotient is a whole number, then 4 and 78,258,955.25 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 | 313,035,821 | |
| -1 | 313,035,821 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 191 | 959 | 1,337 | 1,709 | 11,963 | 26,167 | 183,169 | 234,133 | 326,419 | 1,638,931 | 2,284,933 | 44,719,403 | 313,035,821 |
| -1 | -7 | -137 | -191 | -959 | -1,337 | -1,709 | -11,963 | -26,167 | -183,169 | -234,133 | -326,419 | -1,638,931 | -2,284,933 | -44,719,403 | -313,035,821 |
