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 905,465, 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 | 905,465 | |
| -1 | -905,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 905,465.
Example:
1 x 905,465 = 905,465
and
-1 x -905,465 = 905,465
Notice both answers equal 905,465
With that explanation out of the way, let's continue. Next, we take the number 905,465 and divide it by 2:
905,465 ÷ 2 = 452,732.5
If the quotient is a whole number, then 2 and 452,732.5 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 | 905,465 | |
| -1 | -905,465 |
Now, we try dividing 905,465 by 3:
905,465 ÷ 3 = 301,821.6667
If the quotient is a whole number, then 3 and 301,821.6667 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 | 905,465 | |
| -1 | -905,465 |
Let's try dividing by 4:
905,465 ÷ 4 = 226,366.25
If the quotient is a whole number, then 4 and 226,366.25 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 | 905,465 | |
| -1 | 905,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 163 | 505 | 815 | 1,111 | 1,793 | 5,555 | 8,965 | 16,463 | 82,315 | 181,093 | 905,465 |
| -1 | -5 | -11 | -55 | -101 | -163 | -505 | -815 | -1,111 | -1,793 | -5,555 | -8,965 | -16,463 | -82,315 | -181,093 | -905,465 |
