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 3,829,241, 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 | 3,829,241 | |
| -1 | -3,829,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,829,241.
Example:
1 x 3,829,241 = 3,829,241
and
-1 x -3,829,241 = 3,829,241
Notice both answers equal 3,829,241
With that explanation out of the way, let's continue. Next, we take the number 3,829,241 and divide it by 2:
3,829,241 ÷ 2 = 1,914,620.5
If the quotient is a whole number, then 2 and 1,914,620.5 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 | 3,829,241 | |
| -1 | -3,829,241 |
Now, we try dividing 3,829,241 by 3:
3,829,241 ÷ 3 = 1,276,413.6667
If the quotient is a whole number, then 3 and 1,276,413.6667 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 | 3,829,241 | |
| -1 | -3,829,241 |
Let's try dividing by 4:
3,829,241 ÷ 4 = 957,310.25
If the quotient is a whole number, then 4 and 957,310.25 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 | 3,829,241 | |
| -1 | 3,829,241 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 419 | 481 | 703 | 5,447 | 7,961 | 9,139 | 15,503 | 103,493 | 201,539 | 294,557 | 3,829,241 |
| -1 | -13 | -19 | -37 | -247 | -419 | -481 | -703 | -5,447 | -7,961 | -9,139 | -15,503 | -103,493 | -201,539 | -294,557 | -3,829,241 |
