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 3,844,159, 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 | 3,844,159 | |
| -1 | -3,844,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,844,159.
Example:
1 x 3,844,159 = 3,844,159
and
-1 x -3,844,159 = 3,844,159
Notice both answers equal 3,844,159
With that explanation out of the way, let's continue. Next, we take the number 3,844,159 and divide it by 2:
3,844,159 ÷ 2 = 1,922,079.5
If the quotient is a whole number, then 2 and 1,922,079.5 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 | 3,844,159 | |
| -1 | -3,844,159 |
Now, we try dividing 3,844,159 by 3:
3,844,159 ÷ 3 = 1,281,386.3333
If the quotient is a whole number, then 3 and 1,281,386.3333 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 | 3,844,159 | |
| -1 | -3,844,159 |
Let's try dividing by 4:
3,844,159 ÷ 4 = 961,039.75
If the quotient is a whole number, then 4 and 961,039.75 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 | 3,844,159 | |
| -1 | 3,844,159 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 61 | 187 | 337 | 671 | 1,037 | 3,707 | 5,729 | 11,407 | 20,557 | 63,019 | 226,127 | 349,469 | 3,844,159 |
| -1 | -11 | -17 | -61 | -187 | -337 | -671 | -1,037 | -3,707 | -5,729 | -11,407 | -20,557 | -63,019 | -226,127 | -349,469 | -3,844,159 |
