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 4,940,935, 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 | 4,940,935 | |
| -1 | -4,940,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,940,935.
Example:
1 x 4,940,935 = 4,940,935
and
-1 x -4,940,935 = 4,940,935
Notice both answers equal 4,940,935
With that explanation out of the way, let's continue. Next, we take the number 4,940,935 and divide it by 2:
4,940,935 ÷ 2 = 2,470,467.5
If the quotient is a whole number, then 2 and 2,470,467.5 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 | 4,940,935 | |
| -1 | -4,940,935 |
Now, we try dividing 4,940,935 by 3:
4,940,935 ÷ 3 = 1,646,978.3333
If the quotient is a whole number, then 3 and 1,646,978.3333 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 | 4,940,935 | |
| -1 | -4,940,935 |
Let's try dividing by 4:
4,940,935 ÷ 4 = 1,235,233.75
If the quotient is a whole number, then 4 and 1,235,233.75 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 | 4,940,935 | |
| -1 | 4,940,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 127 | 155 | 251 | 635 | 1,255 | 3,937 | 7,781 | 19,685 | 31,877 | 38,905 | 159,385 | 988,187 | 4,940,935 |
| -1 | -5 | -31 | -127 | -155 | -251 | -635 | -1,255 | -3,937 | -7,781 | -19,685 | -31,877 | -38,905 | -159,385 | -988,187 | -4,940,935 |
