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 307,406,477, 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 | 307,406,477 | |
| -1 | -307,406,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,406,477.
Example:
1 x 307,406,477 = 307,406,477
and
-1 x -307,406,477 = 307,406,477
Notice both answers equal 307,406,477
With that explanation out of the way, let's continue. Next, we take the number 307,406,477 and divide it by 2:
307,406,477 ÷ 2 = 153,703,238.5
If the quotient is a whole number, then 2 and 153,703,238.5 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 | 307,406,477 | |
| -1 | -307,406,477 |
Now, we try dividing 307,406,477 by 3:
307,406,477 ÷ 3 = 102,468,825.6667
If the quotient is a whole number, then 3 and 102,468,825.6667 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 | 307,406,477 | |
| -1 | -307,406,477 |
Let's try dividing by 4:
307,406,477 ÷ 4 = 76,851,619.25
If the quotient is a whole number, then 4 and 76,851,619.25 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 | 307,406,477 | |
| -1 | 307,406,477 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 251 | 1,757 | 5,773 | 7,607 | 40,411 | 53,249 | 174,961 | 1,224,727 | 1,909,357 | 13,365,499 | 43,915,211 | 307,406,477 |
| -1 | -7 | -23 | -161 | -251 | -1,757 | -5,773 | -7,607 | -40,411 | -53,249 | -174,961 | -1,224,727 | -1,909,357 | -13,365,499 | -43,915,211 | -307,406,477 |
