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 3,810,089, 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 | 3,810,089 | |
| -1 | -3,810,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,810,089.
Example:
1 x 3,810,089 = 3,810,089
and
-1 x -3,810,089 = 3,810,089
Notice both answers equal 3,810,089
With that explanation out of the way, let's continue. Next, we take the number 3,810,089 and divide it by 2:
3,810,089 ÷ 2 = 1,905,044.5
If the quotient is a whole number, then 2 and 1,905,044.5 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 | 3,810,089 | |
| -1 | -3,810,089 |
Now, we try dividing 3,810,089 by 3:
3,810,089 ÷ 3 = 1,270,029.6667
If the quotient is a whole number, then 3 and 1,270,029.6667 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 | 3,810,089 | |
| -1 | -3,810,089 |
Let's try dividing by 4:
3,810,089 ÷ 4 = 952,522.25
If the quotient is a whole number, then 4 and 952,522.25 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 | 3,810,089 | |
| -1 | 3,810,089 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 67 | 73 | 779 | 1,273 | 1,387 | 2,747 | 2,993 | 4,891 | 52,193 | 56,867 | 92,929 | 200,531 | 3,810,089 |
| -1 | -19 | -41 | -67 | -73 | -779 | -1,273 | -1,387 | -2,747 | -2,993 | -4,891 | -52,193 | -56,867 | -92,929 | -200,531 | -3,810,089 |
