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 331,470,713, 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 | 331,470,713 | |
| -1 | -331,470,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,470,713.
Example:
1 x 331,470,713 = 331,470,713
and
-1 x -331,470,713 = 331,470,713
Notice both answers equal 331,470,713
With that explanation out of the way, let's continue. Next, we take the number 331,470,713 and divide it by 2:
331,470,713 ÷ 2 = 165,735,356.5
If the quotient is a whole number, then 2 and 165,735,356.5 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 | 331,470,713 | |
| -1 | -331,470,713 |
Now, we try dividing 331,470,713 by 3:
331,470,713 ÷ 3 = 110,490,237.6667
If the quotient is a whole number, then 3 and 110,490,237.6667 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 | 331,470,713 | |
| -1 | -331,470,713 |
Let's try dividing by 4:
331,470,713 ÷ 4 = 82,867,678.25
If the quotient is a whole number, then 4 and 82,867,678.25 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 | 331,470,713 | |
| -1 | 331,470,713 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 1,021 | 2,441 | 7,147 | 17,087 | 19,399 | 46,379 | 135,793 | 324,653 | 2,492,261 | 17,445,827 | 47,352,959 | 331,470,713 |
| -1 | -7 | -19 | -133 | -1,021 | -2,441 | -7,147 | -17,087 | -19,399 | -46,379 | -135,793 | -324,653 | -2,492,261 | -17,445,827 | -47,352,959 | -331,470,713 |
