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 307,500,335, 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 | 307,500,335 | |
| -1 | -307,500,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,500,335.
Example:
1 x 307,500,335 = 307,500,335
and
-1 x -307,500,335 = 307,500,335
Notice both answers equal 307,500,335
With that explanation out of the way, let's continue. Next, we take the number 307,500,335 and divide it by 2:
307,500,335 ÷ 2 = 153,750,167.5
If the quotient is a whole number, then 2 and 153,750,167.5 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 | 307,500,335 | |
| -1 | -307,500,335 |
Now, we try dividing 307,500,335 by 3:
307,500,335 ÷ 3 = 102,500,111.6667
If the quotient is a whole number, then 3 and 102,500,111.6667 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 | 307,500,335 | |
| -1 | -307,500,335 |
Let's try dividing by 4:
307,500,335 ÷ 4 = 76,875,083.75
If the quotient is a whole number, then 4 and 76,875,083.75 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 | 307,500,335 | |
| -1 | 307,500,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 241 | 289 | 883 | 1,205 | 1,445 | 4,097 | 4,415 | 15,011 | 20,485 | 69,649 | 75,055 | 212,803 | 255,187 | 348,245 | 1,064,015 | 1,275,935 | 3,617,651 | 18,088,255 | 61,500,067 | 307,500,335 |
| -1 | -5 | -17 | -85 | -241 | -289 | -883 | -1,205 | -1,445 | -4,097 | -4,415 | -15,011 | -20,485 | -69,649 | -75,055 | -212,803 | -255,187 | -348,245 | -1,064,015 | -1,275,935 | -3,617,651 | -18,088,255 | -61,500,067 | -307,500,335 |
