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 406,847, 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 | 406,847 | |
| -1 | -406,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 406,847.
Example:
1 x 406,847 = 406,847
and
-1 x -406,847 = 406,847
Notice both answers equal 406,847
With that explanation out of the way, let's continue. Next, we take the number 406,847 and divide it by 2:
406,847 ÷ 2 = 203,423.5
If the quotient is a whole number, then 2 and 203,423.5 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 | 406,847 | |
| -1 | -406,847 |
Now, we try dividing 406,847 by 3:
406,847 ÷ 3 = 135,615.6667
If the quotient is a whole number, then 3 and 135,615.6667 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 | 406,847 | |
| -1 | -406,847 |
Let's try dividing by 4:
406,847 ÷ 4 = 101,711.75
If the quotient is a whole number, then 4 and 101,711.75 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 | 406,847 | |
| -1 | 406,847 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 49 | 133 | 161 | 361 | 437 | 931 | 1,127 | 2,527 | 3,059 | 8,303 | 17,689 | 21,413 | 58,121 | 406,847 |
| -1 | -7 | -19 | -23 | -49 | -133 | -161 | -361 | -437 | -931 | -1,127 | -2,527 | -3,059 | -8,303 | -17,689 | -21,413 | -58,121 | -406,847 |
