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 5,108,185, 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 | 5,108,185 | |
| -1 | -5,108,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,108,185.
Example:
1 x 5,108,185 = 5,108,185
and
-1 x -5,108,185 = 5,108,185
Notice both answers equal 5,108,185
With that explanation out of the way, let's continue. Next, we take the number 5,108,185 and divide it by 2:
5,108,185 ÷ 2 = 2,554,092.5
If the quotient is a whole number, then 2 and 2,554,092.5 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 | 5,108,185 | |
| -1 | -5,108,185 |
Now, we try dividing 5,108,185 by 3:
5,108,185 ÷ 3 = 1,702,728.3333
If the quotient is a whole number, then 3 and 1,702,728.3333 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 | 5,108,185 | |
| -1 | -5,108,185 |
Let's try dividing by 4:
5,108,185 ÷ 4 = 1,277,046.25
If the quotient is a whole number, then 4 and 1,277,046.25 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 | 5,108,185 | |
| -1 | 5,108,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 1,033 | 4,945 | 5,165 | 23,759 | 44,419 | 118,795 | 222,095 | 1,021,637 | 5,108,185 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -1,033 | -4,945 | -5,165 | -23,759 | -44,419 | -118,795 | -222,095 | -1,021,637 | -5,108,185 |
