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 3,345,979, 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 | 3,345,979 | |
| -1 | -3,345,979 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,345,979.
Example:
1 x 3,345,979 = 3,345,979
and
-1 x -3,345,979 = 3,345,979
Notice both answers equal 3,345,979
With that explanation out of the way, let's continue. Next, we take the number 3,345,979 and divide it by 2:
3,345,979 ÷ 2 = 1,672,989.5
If the quotient is a whole number, then 2 and 1,672,989.5 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 | 3,345,979 | |
| -1 | -3,345,979 |
Now, we try dividing 3,345,979 by 3:
3,345,979 ÷ 3 = 1,115,326.3333
If the quotient is a whole number, then 3 and 1,115,326.3333 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 | 3,345,979 | |
| -1 | -3,345,979 |
Let's try dividing by 4:
3,345,979 ÷ 4 = 836,494.75
If the quotient is a whole number, then 4 and 836,494.75 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 | 3,345,979 | |
| -1 | 3,345,979 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 83 | 91 | 443 | 581 | 1,079 | 3,101 | 5,759 | 7,553 | 36,769 | 40,313 | 257,383 | 477,997 | 3,345,979 |
| -1 | -7 | -13 | -83 | -91 | -443 | -581 | -1,079 | -3,101 | -5,759 | -7,553 | -36,769 | -40,313 | -257,383 | -477,997 | -3,345,979 |
