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 307,310,047, 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 | 307,310,047 | |
| -1 | -307,310,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,310,047.
Example:
1 x 307,310,047 = 307,310,047
and
-1 x -307,310,047 = 307,310,047
Notice both answers equal 307,310,047
With that explanation out of the way, let's continue. Next, we take the number 307,310,047 and divide it by 2:
307,310,047 ÷ 2 = 153,655,023.5
If the quotient is a whole number, then 2 and 153,655,023.5 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 | 307,310,047 | |
| -1 | -307,310,047 |
Now, we try dividing 307,310,047 by 3:
307,310,047 ÷ 3 = 102,436,682.3333
If the quotient is a whole number, then 3 and 102,436,682.3333 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 | 307,310,047 | |
| -1 | -307,310,047 |
Let's try dividing by 4:
307,310,047 ÷ 4 = 76,827,511.75
If the quotient is a whole number, then 4 and 76,827,511.75 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 | 307,310,047 | |
| -1 | 307,310,047 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 41 | 209 | 451 | 779 | 8,569 | 35,863 | 394,493 | 681,397 | 1,470,383 | 7,495,367 | 16,174,213 | 27,937,277 | 307,310,047 |
| -1 | -11 | -19 | -41 | -209 | -451 | -779 | -8,569 | -35,863 | -394,493 | -681,397 | -1,470,383 | -7,495,367 | -16,174,213 | -27,937,277 | -307,310,047 |
