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 1,328,485, 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 | 1,328,485 | |
| -1 | -1,328,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,328,485.
Example:
1 x 1,328,485 = 1,328,485
and
-1 x -1,328,485 = 1,328,485
Notice both answers equal 1,328,485
With that explanation out of the way, let's continue. Next, we take the number 1,328,485 and divide it by 2:
1,328,485 ÷ 2 = 664,242.5
If the quotient is a whole number, then 2 and 664,242.5 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 | 1,328,485 | |
| -1 | -1,328,485 |
Now, we try dividing 1,328,485 by 3:
1,328,485 ÷ 3 = 442,828.3333
If the quotient is a whole number, then 3 and 442,828.3333 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 | 1,328,485 | |
| -1 | -1,328,485 |
Let's try dividing by 4:
1,328,485 ÷ 4 = 332,121.25
If the quotient is a whole number, then 4 and 332,121.25 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 | 1,328,485 | |
| -1 | 1,328,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 167 | 185 | 215 | 835 | 1,591 | 6,179 | 7,181 | 7,955 | 30,895 | 35,905 | 265,697 | 1,328,485 |
| -1 | -5 | -37 | -43 | -167 | -185 | -215 | -835 | -1,591 | -6,179 | -7,181 | -7,955 | -30,895 | -35,905 | -265,697 | -1,328,485 |
