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 314,391,343, 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 | 314,391,343 | |
| -1 | -314,391,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,391,343.
Example:
1 x 314,391,343 = 314,391,343
and
-1 x -314,391,343 = 314,391,343
Notice both answers equal 314,391,343
With that explanation out of the way, let's continue. Next, we take the number 314,391,343 and divide it by 2:
314,391,343 ÷ 2 = 157,195,671.5
If the quotient is a whole number, then 2 and 157,195,671.5 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 | 314,391,343 | |
| -1 | -314,391,343 |
Now, we try dividing 314,391,343 by 3:
314,391,343 ÷ 3 = 104,797,114.3333
If the quotient is a whole number, then 3 and 104,797,114.3333 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 | 314,391,343 | |
| -1 | -314,391,343 |
Let's try dividing by 4:
314,391,343 ÷ 4 = 78,597,835.75
If the quotient is a whole number, then 4 and 78,597,835.75 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 | 314,391,343 | |
| -1 | 314,391,343 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 173 | 623 | 1,211 | 2,917 | 15,397 | 20,419 | 107,779 | 259,613 | 504,641 | 1,817,291 | 3,532,487 | 44,913,049 | 314,391,343 |
| -1 | -7 | -89 | -173 | -623 | -1,211 | -2,917 | -15,397 | -20,419 | -107,779 | -259,613 | -504,641 | -1,817,291 | -3,532,487 | -44,913,049 | -314,391,343 |
