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 889,105, 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 | 889,105 | |
| -1 | -889,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 889,105.
Example:
1 x 889,105 = 889,105
and
-1 x -889,105 = 889,105
Notice both answers equal 889,105
With that explanation out of the way, let's continue. Next, we take the number 889,105 and divide it by 2:
889,105 ÷ 2 = 444,552.5
If the quotient is a whole number, then 2 and 444,552.5 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 | 889,105 | |
| -1 | -889,105 |
Now, we try dividing 889,105 by 3:
889,105 ÷ 3 = 296,368.3333
If the quotient is a whole number, then 3 and 296,368.3333 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 | 889,105 | |
| -1 | -889,105 |
Let's try dividing by 4:
889,105 ÷ 4 = 222,276.25
If the quotient is a whole number, then 4 and 222,276.25 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 | 889,105 | |
| -1 | 889,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 191 | 245 | 665 | 931 | 955 | 1,337 | 3,629 | 4,655 | 6,685 | 9,359 | 18,145 | 25,403 | 46,795 | 127,015 | 177,821 | 889,105 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -191 | -245 | -665 | -931 | -955 | -1,337 | -3,629 | -4,655 | -6,685 | -9,359 | -18,145 | -25,403 | -46,795 | -127,015 | -177,821 | -889,105 |
