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 7,568,015, 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 | 7,568,015 | |
| -1 | -7,568,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,568,015.
Example:
1 x 7,568,015 = 7,568,015
and
-1 x -7,568,015 = 7,568,015
Notice both answers equal 7,568,015
With that explanation out of the way, let's continue. Next, we take the number 7,568,015 and divide it by 2:
7,568,015 ÷ 2 = 3,784,007.5
If the quotient is a whole number, then 2 and 3,784,007.5 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 | 7,568,015 | |
| -1 | -7,568,015 |
Now, we try dividing 7,568,015 by 3:
7,568,015 ÷ 3 = 2,522,671.6667
If the quotient is a whole number, then 3 and 2,522,671.6667 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 | 7,568,015 | |
| -1 | -7,568,015 |
Let's try dividing by 4:
7,568,015 ÷ 4 = 1,892,003.75
If the quotient is a whole number, then 4 and 1,892,003.75 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 | 7,568,015 | |
| -1 | 7,568,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 16,633 | 83,165 | 116,431 | 216,229 | 582,155 | 1,081,145 | 1,513,603 | 7,568,015 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -16,633 | -83,165 | -116,431 | -216,229 | -582,155 | -1,081,145 | -1,513,603 | -7,568,015 |
