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 4,938,755, 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 | 4,938,755 | |
| -1 | -4,938,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,938,755.
Example:
1 x 4,938,755 = 4,938,755
and
-1 x -4,938,755 = 4,938,755
Notice both answers equal 4,938,755
With that explanation out of the way, let's continue. Next, we take the number 4,938,755 and divide it by 2:
4,938,755 ÷ 2 = 2,469,377.5
If the quotient is a whole number, then 2 and 2,469,377.5 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 | 4,938,755 | |
| -1 | -4,938,755 |
Now, we try dividing 4,938,755 by 3:
4,938,755 ÷ 3 = 1,646,251.6667
If the quotient is a whole number, then 3 and 1,646,251.6667 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 | 4,938,755 | |
| -1 | -4,938,755 |
Let's try dividing by 4:
4,938,755 ÷ 4 = 1,234,688.75
If the quotient is a whole number, then 4 and 1,234,688.75 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 | 4,938,755 | |
| -1 | 4,938,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 485 | 599 | 1,649 | 2,995 | 8,245 | 10,183 | 50,915 | 58,103 | 290,515 | 987,751 | 4,938,755 |
| -1 | -5 | -17 | -85 | -97 | -485 | -599 | -1,649 | -2,995 | -8,245 | -10,183 | -50,915 | -58,103 | -290,515 | -987,751 | -4,938,755 |
