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 815,675, 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 | 815,675 | |
| -1 | -815,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 815,675.
Example:
1 x 815,675 = 815,675
and
-1 x -815,675 = 815,675
Notice both answers equal 815,675
With that explanation out of the way, let's continue. Next, we take the number 815,675 and divide it by 2:
815,675 ÷ 2 = 407,837.5
If the quotient is a whole number, then 2 and 407,837.5 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 | 815,675 | |
| -1 | -815,675 |
Now, we try dividing 815,675 by 3:
815,675 ÷ 3 = 271,891.6667
If the quotient is a whole number, then 3 and 271,891.6667 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 | 815,675 | |
| -1 | -815,675 |
Let's try dividing by 4:
815,675 ÷ 4 = 203,918.75
If the quotient is a whole number, then 4 and 203,918.75 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 | 815,675 | |
| -1 | 815,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 59 | 79 | 175 | 295 | 395 | 413 | 553 | 1,475 | 1,975 | 2,065 | 2,765 | 4,661 | 10,325 | 13,825 | 23,305 | 32,627 | 116,525 | 163,135 | 815,675 |
| -1 | -5 | -7 | -25 | -35 | -59 | -79 | -175 | -295 | -395 | -413 | -553 | -1,475 | -1,975 | -2,065 | -2,765 | -4,661 | -10,325 | -13,825 | -23,305 | -32,627 | -116,525 | -163,135 | -815,675 |
