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 9,302,405, 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 | 9,302,405 | |
| -1 | -9,302,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,302,405.
Example:
1 x 9,302,405 = 9,302,405
and
-1 x -9,302,405 = 9,302,405
Notice both answers equal 9,302,405
With that explanation out of the way, let's continue. Next, we take the number 9,302,405 and divide it by 2:
9,302,405 ÷ 2 = 4,651,202.5
If the quotient is a whole number, then 2 and 4,651,202.5 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 | 9,302,405 | |
| -1 | -9,302,405 |
Now, we try dividing 9,302,405 by 3:
9,302,405 ÷ 3 = 3,100,801.6667
If the quotient is a whole number, then 3 and 3,100,801.6667 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 | 9,302,405 | |
| -1 | -9,302,405 |
Let's try dividing by 4:
9,302,405 ÷ 4 = 2,325,601.25
If the quotient is a whole number, then 4 and 2,325,601.25 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 | 9,302,405 | |
| -1 | 9,302,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 49 | 215 | 245 | 301 | 883 | 1,505 | 2,107 | 4,415 | 6,181 | 10,535 | 30,905 | 37,969 | 43,267 | 189,845 | 216,335 | 265,783 | 1,328,915 | 1,860,481 | 9,302,405 |
| -1 | -5 | -7 | -35 | -43 | -49 | -215 | -245 | -301 | -883 | -1,505 | -2,107 | -4,415 | -6,181 | -10,535 | -30,905 | -37,969 | -43,267 | -189,845 | -216,335 | -265,783 | -1,328,915 | -1,860,481 | -9,302,405 |
