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 2,093,023, 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 | 2,093,023 | |
| -1 | -2,093,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,093,023.
Example:
1 x 2,093,023 = 2,093,023
and
-1 x -2,093,023 = 2,093,023
Notice both answers equal 2,093,023
With that explanation out of the way, let's continue. Next, we take the number 2,093,023 and divide it by 2:
2,093,023 ÷ 2 = 1,046,511.5
If the quotient is a whole number, then 2 and 1,046,511.5 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 | 2,093,023 | |
| -1 | -2,093,023 |
Now, we try dividing 2,093,023 by 3:
2,093,023 ÷ 3 = 697,674.3333
If the quotient is a whole number, then 3 and 697,674.3333 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 | 2,093,023 | |
| -1 | -2,093,023 |
Let's try dividing by 4:
2,093,023 ÷ 4 = 523,255.75
If the quotient is a whole number, then 4 and 523,255.75 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 | 2,093,023 | |
| -1 | 2,093,023 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 53 | 101 | 391 | 901 | 1,219 | 1,717 | 2,323 | 5,353 | 20,723 | 39,491 | 91,001 | 123,119 | 2,093,023 |
| -1 | -17 | -23 | -53 | -101 | -391 | -901 | -1,219 | -1,717 | -2,323 | -5,353 | -20,723 | -39,491 | -91,001 | -123,119 | -2,093,023 |
