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 8,372,345, 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 | 8,372,345 | |
| -1 | -8,372,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,372,345.
Example:
1 x 8,372,345 = 8,372,345
and
-1 x -8,372,345 = 8,372,345
Notice both answers equal 8,372,345
With that explanation out of the way, let's continue. Next, we take the number 8,372,345 and divide it by 2:
8,372,345 ÷ 2 = 4,186,172.5
If the quotient is a whole number, then 2 and 4,186,172.5 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 | 8,372,345 | |
| -1 | -8,372,345 |
Now, we try dividing 8,372,345 by 3:
8,372,345 ÷ 3 = 2,790,781.6667
If the quotient is a whole number, then 3 and 2,790,781.6667 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 | 8,372,345 | |
| -1 | -8,372,345 |
Let's try dividing by 4:
8,372,345 ÷ 4 = 2,093,086.25
If the quotient is a whole number, then 4 and 2,093,086.25 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 | 8,372,345 | |
| -1 | 8,372,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 47 | 115 | 235 | 1,081 | 1,549 | 5,405 | 7,745 | 35,627 | 72,803 | 178,135 | 364,015 | 1,674,469 | 8,372,345 |
| -1 | -5 | -23 | -47 | -115 | -235 | -1,081 | -1,549 | -5,405 | -7,745 | -35,627 | -72,803 | -178,135 | -364,015 | -1,674,469 | -8,372,345 |
