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 3,392,845, 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 | 3,392,845 | |
| -1 | -3,392,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,392,845.
Example:
1 x 3,392,845 = 3,392,845
and
-1 x -3,392,845 = 3,392,845
Notice both answers equal 3,392,845
With that explanation out of the way, let's continue. Next, we take the number 3,392,845 and divide it by 2:
3,392,845 ÷ 2 = 1,696,422.5
If the quotient is a whole number, then 2 and 1,696,422.5 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 | 3,392,845 | |
| -1 | -3,392,845 |
Now, we try dividing 3,392,845 by 3:
3,392,845 ÷ 3 = 1,130,948.3333
If the quotient is a whole number, then 3 and 1,130,948.3333 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 | 3,392,845 | |
| -1 | -3,392,845 |
Let's try dividing by 4:
3,392,845 ÷ 4 = 848,211.25
If the quotient is a whole number, then 4 and 848,211.25 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 | 3,392,845 | |
| -1 | 3,392,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 163 | 181 | 815 | 905 | 3,749 | 4,163 | 18,745 | 20,815 | 29,503 | 147,515 | 678,569 | 3,392,845 |
| -1 | -5 | -23 | -115 | -163 | -181 | -815 | -905 | -3,749 | -4,163 | -18,745 | -20,815 | -29,503 | -147,515 | -678,569 | -3,392,845 |
