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 3,805,241, 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 | 3,805,241 | |
| -1 | -3,805,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,805,241.
Example:
1 x 3,805,241 = 3,805,241
and
-1 x -3,805,241 = 3,805,241
Notice both answers equal 3,805,241
With that explanation out of the way, let's continue. Next, we take the number 3,805,241 and divide it by 2:
3,805,241 ÷ 2 = 1,902,620.5
If the quotient is a whole number, then 2 and 1,902,620.5 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 | 3,805,241 | |
| -1 | -3,805,241 |
Now, we try dividing 3,805,241 by 3:
3,805,241 ÷ 3 = 1,268,413.6667
If the quotient is a whole number, then 3 and 1,268,413.6667 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 | 3,805,241 | |
| -1 | -3,805,241 |
Let's try dividing by 4:
3,805,241 ÷ 4 = 951,310.25
If the quotient is a whole number, then 4 and 951,310.25 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 | 3,805,241 | |
| -1 | 3,805,241 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 61 | 107 | 583 | 671 | 1,177 | 3,233 | 5,671 | 6,527 | 35,563 | 62,381 | 71,797 | 345,931 | 3,805,241 |
| -1 | -11 | -53 | -61 | -107 | -583 | -671 | -1,177 | -3,233 | -5,671 | -6,527 | -35,563 | -62,381 | -71,797 | -345,931 | -3,805,241 |
