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 909,685, 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 | 909,685 | |
| -1 | -909,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 909,685.
Example:
1 x 909,685 = 909,685
and
-1 x -909,685 = 909,685
Notice both answers equal 909,685
With that explanation out of the way, let's continue. Next, we take the number 909,685 and divide it by 2:
909,685 ÷ 2 = 454,842.5
If the quotient is a whole number, then 2 and 454,842.5 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 | 909,685 | |
| -1 | -909,685 |
Now, we try dividing 909,685 by 3:
909,685 ÷ 3 = 303,228.3333
If the quotient is a whole number, then 3 and 303,228.3333 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 | 909,685 | |
| -1 | -909,685 |
Let's try dividing by 4:
909,685 ÷ 4 = 227,421.25
If the quotient is a whole number, then 4 and 227,421.25 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 | 909,685 | |
| -1 | 909,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 79 | 235 | 245 | 329 | 395 | 553 | 1,645 | 2,303 | 2,765 | 3,713 | 3,871 | 11,515 | 18,565 | 19,355 | 25,991 | 129,955 | 181,937 | 909,685 |
| -1 | -5 | -7 | -35 | -47 | -49 | -79 | -235 | -245 | -329 | -395 | -553 | -1,645 | -2,303 | -2,765 | -3,713 | -3,871 | -11,515 | -18,565 | -19,355 | -25,991 | -129,955 | -181,937 | -909,685 |
