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 3,378,349, 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 | 3,378,349 | |
| -1 | -3,378,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,378,349.
Example:
1 x 3,378,349 = 3,378,349
and
-1 x -3,378,349 = 3,378,349
Notice both answers equal 3,378,349
With that explanation out of the way, let's continue. Next, we take the number 3,378,349 and divide it by 2:
3,378,349 ÷ 2 = 1,689,174.5
If the quotient is a whole number, then 2 and 1,689,174.5 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 | 3,378,349 | |
| -1 | -3,378,349 |
Now, we try dividing 3,378,349 by 3:
3,378,349 ÷ 3 = 1,126,116.3333
If the quotient is a whole number, then 3 and 1,126,116.3333 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 | 3,378,349 | |
| -1 | -3,378,349 |
Let's try dividing by 4:
3,378,349 ÷ 4 = 844,587.25
If the quotient is a whole number, then 4 and 844,587.25 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 | 3,378,349 | |
| -1 | 3,378,349 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 83 | 101 | 403 | 1,079 | 1,313 | 2,573 | 3,131 | 8,383 | 33,449 | 40,703 | 108,979 | 259,873 | 3,378,349 |
| -1 | -13 | -31 | -83 | -101 | -403 | -1,079 | -1,313 | -2,573 | -3,131 | -8,383 | -33,449 | -40,703 | -108,979 | -259,873 | -3,378,349 |
