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 5,068,105, 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 | 5,068,105 | |
| -1 | -5,068,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,068,105.
Example:
1 x 5,068,105 = 5,068,105
and
-1 x -5,068,105 = 5,068,105
Notice both answers equal 5,068,105
With that explanation out of the way, let's continue. Next, we take the number 5,068,105 and divide it by 2:
5,068,105 ÷ 2 = 2,534,052.5
If the quotient is a whole number, then 2 and 2,534,052.5 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 | 5,068,105 | |
| -1 | -5,068,105 |
Now, we try dividing 5,068,105 by 3:
5,068,105 ÷ 3 = 1,689,368.3333
If the quotient is a whole number, then 3 and 1,689,368.3333 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 | 5,068,105 | |
| -1 | -5,068,105 |
Let's try dividing by 4:
5,068,105 ÷ 4 = 1,267,026.25
If the quotient is a whole number, then 4 and 1,267,026.25 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 | 5,068,105 | |
| -1 | 5,068,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 1,627 | 3,115 | 8,135 | 11,389 | 56,945 | 144,803 | 724,015 | 1,013,621 | 5,068,105 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -1,627 | -3,115 | -8,135 | -11,389 | -56,945 | -144,803 | -724,015 | -1,013,621 | -5,068,105 |
