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 814,775, 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 | 814,775 | |
| -1 | -814,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 814,775.
Example:
1 x 814,775 = 814,775
and
-1 x -814,775 = 814,775
Notice both answers equal 814,775
With that explanation out of the way, let's continue. Next, we take the number 814,775 and divide it by 2:
814,775 ÷ 2 = 407,387.5
If the quotient is a whole number, then 2 and 407,387.5 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 | 814,775 | |
| -1 | -814,775 |
Now, we try dividing 814,775 by 3:
814,775 ÷ 3 = 271,591.6667
If the quotient is a whole number, then 3 and 271,591.6667 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 | 814,775 | |
| -1 | -814,775 |
Let's try dividing by 4:
814,775 ÷ 4 = 203,693.75
If the quotient is a whole number, then 4 and 203,693.75 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 | 814,775 | |
| -1 | 814,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 25 | 65 | 109 | 115 | 299 | 325 | 545 | 575 | 1,417 | 1,495 | 2,507 | 2,725 | 7,085 | 7,475 | 12,535 | 32,591 | 35,425 | 62,675 | 162,955 | 814,775 |
| -1 | -5 | -13 | -23 | -25 | -65 | -109 | -115 | -299 | -325 | -545 | -575 | -1,417 | -1,495 | -2,507 | -2,725 | -7,085 | -7,475 | -12,535 | -32,591 | -35,425 | -62,675 | -162,955 | -814,775 |
