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 5,128,885, 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 | 5,128,885 | |
| -1 | -5,128,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,128,885.
Example:
1 x 5,128,885 = 5,128,885
and
-1 x -5,128,885 = 5,128,885
Notice both answers equal 5,128,885
With that explanation out of the way, let's continue. Next, we take the number 5,128,885 and divide it by 2:
5,128,885 ÷ 2 = 2,564,442.5
If the quotient is a whole number, then 2 and 2,564,442.5 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 | 5,128,885 | |
| -1 | -5,128,885 |
Now, we try dividing 5,128,885 by 3:
5,128,885 ÷ 3 = 1,709,628.3333
If the quotient is a whole number, then 3 and 1,709,628.3333 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 | 5,128,885 | |
| -1 | -5,128,885 |
Let's try dividing by 4:
5,128,885 ÷ 4 = 1,282,221.25
If the quotient is a whole number, then 4 and 1,282,221.25 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 | 5,128,885 | |
| -1 | 5,128,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 103 | 115 | 433 | 515 | 2,165 | 2,369 | 9,959 | 11,845 | 44,599 | 49,795 | 222,995 | 1,025,777 | 5,128,885 |
| -1 | -5 | -23 | -103 | -115 | -433 | -515 | -2,165 | -2,369 | -9,959 | -11,845 | -44,599 | -49,795 | -222,995 | -1,025,777 | -5,128,885 |
