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 3,853,259, 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 | 3,853,259 | |
| -1 | -3,853,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,853,259.
Example:
1 x 3,853,259 = 3,853,259
and
-1 x -3,853,259 = 3,853,259
Notice both answers equal 3,853,259
With that explanation out of the way, let's continue. Next, we take the number 3,853,259 and divide it by 2:
3,853,259 ÷ 2 = 1,926,629.5
If the quotient is a whole number, then 2 and 1,926,629.5 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 | 3,853,259 | |
| -1 | -3,853,259 |
Now, we try dividing 3,853,259 by 3:
3,853,259 ÷ 3 = 1,284,419.6667
If the quotient is a whole number, then 3 and 1,284,419.6667 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 | 3,853,259 | |
| -1 | -3,853,259 |
Let's try dividing by 4:
3,853,259 ÷ 4 = 963,314.75
If the quotient is a whole number, then 4 and 963,314.75 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 | 3,853,259 | |
| -1 | 3,853,259 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 53 | 109 | 667 | 1,219 | 1,537 | 2,507 | 3,161 | 5,777 | 35,351 | 72,703 | 132,871 | 167,533 | 3,853,259 |
| -1 | -23 | -29 | -53 | -109 | -667 | -1,219 | -1,537 | -2,507 | -3,161 | -5,777 | -35,351 | -72,703 | -132,871 | -167,533 | -3,853,259 |
