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 1,819,345, 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 | 1,819,345 | |
| -1 | -1,819,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,819,345.
Example:
1 x 1,819,345 = 1,819,345
and
-1 x -1,819,345 = 1,819,345
Notice both answers equal 1,819,345
With that explanation out of the way, let's continue. Next, we take the number 1,819,345 and divide it by 2:
1,819,345 ÷ 2 = 909,672.5
If the quotient is a whole number, then 2 and 909,672.5 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 | 1,819,345 | |
| -1 | -1,819,345 |
Now, we try dividing 1,819,345 by 3:
1,819,345 ÷ 3 = 606,448.3333
If the quotient is a whole number, then 3 and 606,448.3333 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 | 1,819,345 | |
| -1 | -1,819,345 |
Let's try dividing by 4:
1,819,345 ÷ 4 = 454,836.25
If the quotient is a whole number, then 4 and 454,836.25 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 | 1,819,345 | |
| -1 | 1,819,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 1,741 | 8,705 | 19,151 | 33,079 | 95,755 | 165,395 | 363,869 | 1,819,345 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -1,741 | -8,705 | -19,151 | -33,079 | -95,755 | -165,395 | -363,869 | -1,819,345 |
