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 4,026,935, 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 | 4,026,935 | |
| -1 | -4,026,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,026,935.
Example:
1 x 4,026,935 = 4,026,935
and
-1 x -4,026,935 = 4,026,935
Notice both answers equal 4,026,935
With that explanation out of the way, let's continue. Next, we take the number 4,026,935 and divide it by 2:
4,026,935 ÷ 2 = 2,013,467.5
If the quotient is a whole number, then 2 and 2,013,467.5 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 | 4,026,935 | |
| -1 | -4,026,935 |
Now, we try dividing 4,026,935 by 3:
4,026,935 ÷ 3 = 1,342,311.6667
If the quotient is a whole number, then 3 and 1,342,311.6667 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 | 4,026,935 | |
| -1 | -4,026,935 |
Let's try dividing by 4:
4,026,935 ÷ 4 = 1,006,733.75
If the quotient is a whole number, then 4 and 1,006,733.75 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 | 4,026,935 | |
| -1 | 4,026,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 211 | 347 | 1,055 | 1,735 | 2,321 | 3,817 | 11,605 | 19,085 | 73,217 | 366,085 | 805,387 | 4,026,935 |
| -1 | -5 | -11 | -55 | -211 | -347 | -1,055 | -1,735 | -2,321 | -3,817 | -11,605 | -19,085 | -73,217 | -366,085 | -805,387 | -4,026,935 |
