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 307,623,337, 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 | 307,623,337 | |
| -1 | -307,623,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,623,337.
Example:
1 x 307,623,337 = 307,623,337
and
-1 x -307,623,337 = 307,623,337
Notice both answers equal 307,623,337
With that explanation out of the way, let's continue. Next, we take the number 307,623,337 and divide it by 2:
307,623,337 ÷ 2 = 153,811,668.5
If the quotient is a whole number, then 2 and 153,811,668.5 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 | 307,623,337 | |
| -1 | -307,623,337 |
Now, we try dividing 307,623,337 by 3:
307,623,337 ÷ 3 = 102,541,112.3333
If the quotient is a whole number, then 3 and 102,541,112.3333 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 | 307,623,337 | |
| -1 | -307,623,337 |
Let's try dividing by 4:
307,623,337 ÷ 4 = 76,905,834.25
If the quotient is a whole number, then 4 and 76,905,834.25 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 | 307,623,337 | |
| -1 | 307,623,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 127 | 293 | 889 | 1,181 | 2,051 | 8,267 | 37,211 | 149,987 | 260,477 | 346,033 | 1,049,909 | 2,422,231 | 43,946,191 | 307,623,337 |
| -1 | -7 | -127 | -293 | -889 | -1,181 | -2,051 | -8,267 | -37,211 | -149,987 | -260,477 | -346,033 | -1,049,909 | -2,422,231 | -43,946,191 | -307,623,337 |
