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 7,384,585, 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 | 7,384,585 | |
| -1 | -7,384,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,384,585.
Example:
1 x 7,384,585 = 7,384,585
and
-1 x -7,384,585 = 7,384,585
Notice both answers equal 7,384,585
With that explanation out of the way, let's continue. Next, we take the number 7,384,585 and divide it by 2:
7,384,585 ÷ 2 = 3,692,292.5
If the quotient is a whole number, then 2 and 3,692,292.5 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 | 7,384,585 | |
| -1 | -7,384,585 |
Now, we try dividing 7,384,585 by 3:
7,384,585 ÷ 3 = 2,461,528.3333
If the quotient is a whole number, then 3 and 2,461,528.3333 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 | 7,384,585 | |
| -1 | -7,384,585 |
Let's try dividing by 4:
7,384,585 ÷ 4 = 1,846,146.25
If the quotient is a whole number, then 4 and 1,846,146.25 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 | 7,384,585 | |
| -1 | 7,384,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 515 | 1,103 | 1,339 | 5,515 | 6,695 | 14,339 | 71,695 | 113,609 | 568,045 | 1,476,917 | 7,384,585 |
| -1 | -5 | -13 | -65 | -103 | -515 | -1,103 | -1,339 | -5,515 | -6,695 | -14,339 | -71,695 | -113,609 | -568,045 | -1,476,917 | -7,384,585 |
