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 7,056,785, 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 | 7,056,785 | |
| -1 | -7,056,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,056,785.
Example:
1 x 7,056,785 = 7,056,785
and
-1 x -7,056,785 = 7,056,785
Notice both answers equal 7,056,785
With that explanation out of the way, let's continue. Next, we take the number 7,056,785 and divide it by 2:
7,056,785 ÷ 2 = 3,528,392.5
If the quotient is a whole number, then 2 and 3,528,392.5 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 | 7,056,785 | |
| -1 | -7,056,785 |
Now, we try dividing 7,056,785 by 3:
7,056,785 ÷ 3 = 2,352,261.6667
If the quotient is a whole number, then 3 and 2,352,261.6667 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 | 7,056,785 | |
| -1 | -7,056,785 |
Let's try dividing by 4:
7,056,785 ÷ 4 = 1,764,196.25
If the quotient is a whole number, then 4 and 1,764,196.25 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 | 7,056,785 | |
| -1 | 7,056,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 1,037 | 1,361 | 5,185 | 6,805 | 23,137 | 83,021 | 115,685 | 415,105 | 1,411,357 | 7,056,785 |
| -1 | -5 | -17 | -61 | -85 | -305 | -1,037 | -1,361 | -5,185 | -6,805 | -23,137 | -83,021 | -115,685 | -415,105 | -1,411,357 | -7,056,785 |
