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 3,390,695, 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 | 3,390,695 | |
| -1 | -3,390,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,390,695.
Example:
1 x 3,390,695 = 3,390,695
and
-1 x -3,390,695 = 3,390,695
Notice both answers equal 3,390,695
With that explanation out of the way, let's continue. Next, we take the number 3,390,695 and divide it by 2:
3,390,695 ÷ 2 = 1,695,347.5
If the quotient is a whole number, then 2 and 1,695,347.5 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 | 3,390,695 | |
| -1 | -3,390,695 |
Now, we try dividing 3,390,695 by 3:
3,390,695 ÷ 3 = 1,130,231.6667
If the quotient is a whole number, then 3 and 1,130,231.6667 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 | 3,390,695 | |
| -1 | -3,390,695 |
Let's try dividing by 4:
3,390,695 ÷ 4 = 847,673.75
If the quotient is a whole number, then 4 and 847,673.75 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 | 3,390,695 | |
| -1 | 3,390,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 8,807 | 44,035 | 61,649 | 96,877 | 308,245 | 484,385 | 678,139 | 3,390,695 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -8,807 | -44,035 | -61,649 | -96,877 | -308,245 | -484,385 | -678,139 | -3,390,695 |
