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 4,040,179, 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 | 4,040,179 | |
| -1 | -4,040,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,040,179.
Example:
1 x 4,040,179 = 4,040,179
and
-1 x -4,040,179 = 4,040,179
Notice both answers equal 4,040,179
With that explanation out of the way, let's continue. Next, we take the number 4,040,179 and divide it by 2:
4,040,179 ÷ 2 = 2,020,089.5
If the quotient is a whole number, then 2 and 2,020,089.5 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 | 4,040,179 | |
| -1 | -4,040,179 |
Now, we try dividing 4,040,179 by 3:
4,040,179 ÷ 3 = 1,346,726.3333
If the quotient is a whole number, then 3 and 1,346,726.3333 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 | 4,040,179 | |
| -1 | -4,040,179 |
Let's try dividing by 4:
4,040,179 ÷ 4 = 1,010,044.75
If the quotient is a whole number, then 4 and 1,010,044.75 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 | 4,040,179 | |
| -1 | 4,040,179 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 209 | 247 | 1,487 | 2,717 | 16,357 | 19,331 | 28,253 | 212,641 | 310,783 | 367,289 | 4,040,179 |
| -1 | -11 | -13 | -19 | -143 | -209 | -247 | -1,487 | -2,717 | -16,357 | -19,331 | -28,253 | -212,641 | -310,783 | -367,289 | -4,040,179 |
