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 978,835, 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 | 978,835 | |
| -1 | -978,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 978,835.
Example:
1 x 978,835 = 978,835
and
-1 x -978,835 = 978,835
Notice both answers equal 978,835
With that explanation out of the way, let's continue. Next, we take the number 978,835 and divide it by 2:
978,835 ÷ 2 = 489,417.5
If the quotient is a whole number, then 2 and 489,417.5 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 | 978,835 | |
| -1 | -978,835 |
Now, we try dividing 978,835 by 3:
978,835 ÷ 3 = 326,278.3333
If the quotient is a whole number, then 3 and 326,278.3333 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 | 978,835 | |
| -1 | -978,835 |
Let's try dividing by 4:
978,835 ÷ 4 = 244,708.75
If the quotient is a whole number, then 4 and 244,708.75 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 | 978,835 | |
| -1 | 978,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 37 | 55 | 65 | 143 | 185 | 407 | 481 | 715 | 1,369 | 2,035 | 2,405 | 5,291 | 6,845 | 15,059 | 17,797 | 26,455 | 75,295 | 88,985 | 195,767 | 978,835 |
| -1 | -5 | -11 | -13 | -37 | -55 | -65 | -143 | -185 | -407 | -481 | -715 | -1,369 | -2,035 | -2,405 | -5,291 | -6,845 | -15,059 | -17,797 | -26,455 | -75,295 | -88,985 | -195,767 | -978,835 |
