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 1,085,975, 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 | 1,085,975 | |
| -1 | -1,085,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,085,975.
Example:
1 x 1,085,975 = 1,085,975
and
-1 x -1,085,975 = 1,085,975
Notice both answers equal 1,085,975
With that explanation out of the way, let's continue. Next, we take the number 1,085,975 and divide it by 2:
1,085,975 ÷ 2 = 542,987.5
If the quotient is a whole number, then 2 and 542,987.5 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 | 1,085,975 | |
| -1 | -1,085,975 |
Now, we try dividing 1,085,975 by 3:
1,085,975 ÷ 3 = 361,991.6667
If the quotient is a whole number, then 3 and 361,991.6667 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 | 1,085,975 | |
| -1 | -1,085,975 |
Let's try dividing by 4:
1,085,975 ÷ 4 = 271,493.75
If the quotient is a whole number, then 4 and 271,493.75 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 | 1,085,975 | |
| -1 | 1,085,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 359 | 605 | 1,795 | 3,025 | 3,949 | 8,975 | 19,745 | 43,439 | 98,725 | 217,195 | 1,085,975 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -359 | -605 | -1,795 | -3,025 | -3,949 | -8,975 | -19,745 | -43,439 | -98,725 | -217,195 | -1,085,975 |
