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 3,811,073, 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 | 3,811,073 | |
| -1 | -3,811,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,811,073.
Example:
1 x 3,811,073 = 3,811,073
and
-1 x -3,811,073 = 3,811,073
Notice both answers equal 3,811,073
With that explanation out of the way, let's continue. Next, we take the number 3,811,073 and divide it by 2:
3,811,073 ÷ 2 = 1,905,536.5
If the quotient is a whole number, then 2 and 1,905,536.5 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 | 3,811,073 | |
| -1 | -3,811,073 |
Now, we try dividing 3,811,073 by 3:
3,811,073 ÷ 3 = 1,270,357.6667
If the quotient is a whole number, then 3 and 1,270,357.6667 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 | 3,811,073 | |
| -1 | -3,811,073 |
Let's try dividing by 4:
3,811,073 ÷ 4 = 952,768.25
If the quotient is a whole number, then 4 and 952,768.25 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 | 3,811,073 | |
| -1 | 3,811,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 271 | 287 | 343 | 1,897 | 2,009 | 11,111 | 13,279 | 14,063 | 77,777 | 92,953 | 544,439 | 3,811,073 |
| -1 | -7 | -41 | -49 | -271 | -287 | -343 | -1,897 | -2,009 | -11,111 | -13,279 | -14,063 | -77,777 | -92,953 | -544,439 | -3,811,073 |
