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 4,034,821, 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 | 4,034,821 | |
| -1 | -4,034,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,034,821.
Example:
1 x 4,034,821 = 4,034,821
and
-1 x -4,034,821 = 4,034,821
Notice both answers equal 4,034,821
With that explanation out of the way, let's continue. Next, we take the number 4,034,821 and divide it by 2:
4,034,821 ÷ 2 = 2,017,410.5
If the quotient is a whole number, then 2 and 2,017,410.5 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 | 4,034,821 | |
| -1 | -4,034,821 |
Now, we try dividing 4,034,821 by 3:
4,034,821 ÷ 3 = 1,344,940.3333
If the quotient is a whole number, then 3 and 1,344,940.3333 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 | 4,034,821 | |
| -1 | -4,034,821 |
Let's try dividing by 4:
4,034,821 ÷ 4 = 1,008,705.25
If the quotient is a whole number, then 4 and 1,008,705.25 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 | 4,034,821 | |
| -1 | 4,034,821 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 1,319 | 3,059 | 9,233 | 25,061 | 30,337 | 175,427 | 212,359 | 576,403 | 4,034,821 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -1,319 | -3,059 | -9,233 | -25,061 | -30,337 | -175,427 | -212,359 | -576,403 | -4,034,821 |
