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 3,320,345, 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 | 3,320,345 | |
| -1 | -3,320,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,320,345.
Example:
1 x 3,320,345 = 3,320,345
and
-1 x -3,320,345 = 3,320,345
Notice both answers equal 3,320,345
With that explanation out of the way, let's continue. Next, we take the number 3,320,345 and divide it by 2:
3,320,345 ÷ 2 = 1,660,172.5
If the quotient is a whole number, then 2 and 1,660,172.5 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 | 3,320,345 | |
| -1 | -3,320,345 |
Now, we try dividing 3,320,345 by 3:
3,320,345 ÷ 3 = 1,106,781.6667
If the quotient is a whole number, then 3 and 1,106,781.6667 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 | 3,320,345 | |
| -1 | -3,320,345 |
Let's try dividing by 4:
3,320,345 ÷ 4 = 830,086.25
If the quotient is a whole number, then 4 and 830,086.25 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 | 3,320,345 | |
| -1 | 3,320,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 4,993 | 24,965 | 34,951 | 94,867 | 174,755 | 474,335 | 664,069 | 3,320,345 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -4,993 | -24,965 | -34,951 | -94,867 | -174,755 | -474,335 | -664,069 | -3,320,345 |
