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 1,534,885, 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 | 1,534,885 | |
| -1 | -1,534,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,534,885.
Example:
1 x 1,534,885 = 1,534,885
and
-1 x -1,534,885 = 1,534,885
Notice both answers equal 1,534,885
With that explanation out of the way, let's continue. Next, we take the number 1,534,885 and divide it by 2:
1,534,885 ÷ 2 = 767,442.5
If the quotient is a whole number, then 2 and 767,442.5 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 | 1,534,885 | |
| -1 | -1,534,885 |
Now, we try dividing 1,534,885 by 3:
1,534,885 ÷ 3 = 511,628.3333
If the quotient is a whole number, then 3 and 511,628.3333 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 | 1,534,885 | |
| -1 | -1,534,885 |
Let's try dividing by 4:
1,534,885 ÷ 4 = 383,721.25
If the quotient is a whole number, then 4 and 383,721.25 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 | 1,534,885 | |
| -1 | 1,534,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 59 | 121 | 215 | 295 | 473 | 605 | 649 | 2,365 | 2,537 | 3,245 | 5,203 | 7,139 | 12,685 | 26,015 | 27,907 | 35,695 | 139,535 | 306,977 | 1,534,885 |
| -1 | -5 | -11 | -43 | -55 | -59 | -121 | -215 | -295 | -473 | -605 | -649 | -2,365 | -2,537 | -3,245 | -5,203 | -7,139 | -12,685 | -26,015 | -27,907 | -35,695 | -139,535 | -306,977 | -1,534,885 |
