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 313,100,297, 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 | 313,100,297 | |
| -1 | -313,100,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,100,297.
Example:
1 x 313,100,297 = 313,100,297
and
-1 x -313,100,297 = 313,100,297
Notice both answers equal 313,100,297
With that explanation out of the way, let's continue. Next, we take the number 313,100,297 and divide it by 2:
313,100,297 ÷ 2 = 156,550,148.5
If the quotient is a whole number, then 2 and 156,550,148.5 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 | 313,100,297 | |
| -1 | -313,100,297 |
Now, we try dividing 313,100,297 by 3:
313,100,297 ÷ 3 = 104,366,765.6667
If the quotient is a whole number, then 3 and 104,366,765.6667 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 | 313,100,297 | |
| -1 | -313,100,297 |
Let's try dividing by 4:
313,100,297 ÷ 4 = 78,275,074.25
If the quotient is a whole number, then 4 and 78,275,074.25 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 | 313,100,297 | |
| -1 | 313,100,297 |
If you did it right, you will end up with this table:
| 1 | 19 | 107 | 337 | 457 | 2,033 | 6,403 | 8,683 | 36,059 | 48,899 | 154,009 | 685,121 | 929,081 | 2,926,171 | 16,478,963 | 313,100,297 |
| -1 | -19 | -107 | -337 | -457 | -2,033 | -6,403 | -8,683 | -36,059 | -48,899 | -154,009 | -685,121 | -929,081 | -2,926,171 | -16,478,963 | -313,100,297 |
